Thanks sparkstech and the second part to which you answered should have been a comma. I didnt mean i posted it in the tech section cause it wasnt a bose system but to find out if the 2 were seperate outputs. I read it twice and it does come off like that and i agree with the name has nothing to do with the knowledge of the situation. I really do appreciate the help. So if i understand right there can be only one cut wire that will make both speakers not work. Thanks again JC

Yeah, and with as many miles as you have on your truck already I would bet its broken in the drivers door wire loom. That's the door you open and shut most often.

when you hit a bump or something hard enough the wire lifts off the metal, and the next time you start the truck the speakers work, than it falls back on the metal and stops again.

 

Just pull your speakers out and test them by hooking them up to any home stereo with speaker wire jacks at the back...just to make sure they work fine. Also look for water damage on them.

 

Than attach a multimeter to one wire with the other side attached to a ground point and set the meter on continuity test. Than jiggle the wire around. Than do it with the other 3 wires for the front speakers.

 

Also, test both wires in each side for continuity with each other.

That will get you started...if you cant find a problem this way...you may have to pull the dash and stereo and meter the whole wire for continuity fro the plug to the speaker.

 

You can also check for voltage at the speaker inputs.

Correct a broken wire on the left can cause an issue with the right and vice versa.

I would start on the left side too for the same reason. I would stay away from using a speaker that doesn't match the system for testing. A speaker with the wrong impedence can throw you off. I would do the voltage testing instead of the resistance to gnd check because an open wire will cause the same issue as a grounded one here.

Yeah the voltage is the quick and dirty, I like doing both just to make sure.

 

Of course I am an electro-mechanical tech and this is how I was taught to trouble shoot electronics. I am much better on the Mechanical side than I am on the electro side.. :D:cool::D

Aight to get yall up to date to know what i need to do next...

Yesterday i was riding down the rode and my front drivers side door kicked on. And the passanger door still wasnt working. Today when i turn the truck on neither are working.

So i tested for volts and this is what i come up with that has me confussed as crap...

Front Driver door- NO VOLTS EITHER WIRE

Front Pas. Door- 7.25 volts both wires.

 

Now Could it be possible that the driver door is shorted and the passanger door is busted or not working. I did an ohms test on Both sides and the bothed ohmed telling me that it the curcuit is complete i believe. Just at a loss right now.

Just because you have the voltage you expect on the passenger side doesn't mean that the driver side isn't still taking the driver down. Fix the issue on the left and worry about the right after that if it still doesn't work. I would start the search for the left side issue at the door pass through, that is most likely the area where the broken wire(s) are.

Did you check from each wire to ground?

 

If the meter reads a number, or beeps (if you have that feature), it means that you have a complete path to ground...a.k.a. a short.

Yes i did each wire to a ground on both sides and that is where i got the numbers listed above. I pulled the door rubber piece back but the wires were taped with plastic wrap around them so i didnt get a chance to look at it due to darkness. But i will fix my wire problem on the left when i find it and then see if the right fixes or not. Thanks again guys.

If that doesn't fix the other side it will be easy enough, since you have it all apart, to just take the left speaker and swap it with the right to see if it is the speaker or not.

Exact same thing happened to me coming home from work this past friday night. So far I've just adjusted settings to where the sound audio is mainly coming from the back and slightly from the front tweeters for temporary purposes. I'm thinking about taking it into the dealers, but wanted to do a little research first. Keep me posted man with the outcome. It would be greatly appreciated.

 

By the way i have a 2008 Chevy Silverado 1500 with approx. 20k miles

 

About 3 months ago my front door speakers quit working. Drivers and passanger side. I thought it might be a short in the Front input on the CD player. Well the tweeters still work when i fade to the front which tells me that they are hooked into the Front input as well. My question is are these speakers on seperate inputs or is it possible both my front speakers blew at the same time. up to 3 weeks after this they would randomly kick on and off and didnt sound busted and played fine. Turn my truck off and next time i turn it on they are not working. I have a little audio knowledge but i am at a loss on this one?

G-Mizzle or JCARP,

 

This thread describes exactly what I've got going on with my '06 Silverado. Only back right speaker working...the other three were intermittent for a couple of weeks, but now they're basically dead, only very faint sound coming from them.

 

Have either of you figured anything out? I plan on ripping into the wiring this weekend, but was hoping one of you had a breakthrough.

 

Thanks.

      Low fuel pressure after installing new fuel pump

      Replace the fuel pump with an OEM AC-Delco.

      Low fuel pressure after installing new fuel pump

      By Gilkey96 · Posted

      Hello, first time posting here. I have an 03 Chevy 1500HD with the 6 liter gas engine. The truck ran fine until the fuel pump died on me and had to get it towed. Replaced the fuel pump with a precision pump from O’rileys and changed the fuel filter while I was there. The truck will run and drive now but it wants to idle around 500 rpm when in drive and it tries to stall if you touch the gas. It drives fine though, just doesn’t want to idle. Put a fuel pressure gauge on the rail and only have 50 psi. I guess these trucks should have 55-62 psi to run right. I thought the regulator might be the issue because when I would unplug the vacuum hose it jumped to 56 psi. Replaced the regulator and no change. The only thing I can think of is that I was sold a faulty fuel pump. Any help would be appreciated because I’d rather not have to take the bed off again if I don’t have too. Thank you!

      AFM Experience

      By diyer2 · Posted

      I've been wrenching on GM trucks for 17 years. And I need to get something off my chest because it's been weighing on me for a long time. After all that time, all those motors, all those people standing in my bay, I've figured out there are really only two kinds of owners. The ones who already know about this. And the ones who are about to find out the hard way. A guy came into my shop a few weeks back in a 2018 Silverado 5.3. Sharp guy, maybe 35. Knew his truck cold. He'd been on the forums, read the threads, done his homework. He only rolled in so I could double-check a little module he'd already plugged in himself. Wanted a second set of eyes on it. Ten minutes, in and out, drove off happy. Two days later, a completely different story walked through the same door. Older fella this time, in a 2016 Sierra. Gorgeous truck, clearly babied, not a scratch on it. Wedding ring. Looked like a guy who took care of his stuff. He was in because his engine had started knocking on the way to work. And by the time I got the valve cover off, I already knew it was too late. Lifter collapsed. Cylinder 5. Camshaft chewed up. The whole top end shot. Same kind of truck. Same motor. Same roads, probably the same dealer. The only thing separating those two men was information. I've been at this since 2008, and I've worked on everything GM puts out. Silverados. Sierras. Tahoes. Yukons. Suburbans. Escalades. The 5.3 and the 6.2. Doesn't matter which badge is on the tailgate. They all carry the same problem. So here's the information one of those guys had and the other one didn't. It's called Active Fuel Management. AFM. GM started building it into their V6s and V8s back in 2007 to squeeze out a little better mileage on the highway. Maybe a mile or two a gallon. All to hit government fuel economy numbers. The way it works, the motor quietly shuts down half its cylinders when you're just cruising along. And the little lifters that pull that off have a tiny pin inside them that's constantly clicking in and out. Lock, unlock, lock, unlock. Hundreds of times a drive. Thousands of times a week. Eventually one of those pins wears through. The lifter drops. And it starts grinding the camshaft down like a chisel on butter. And what nobody tells you is that the shudder you feel around 40 or 50 mph? That's the system cycling. Every single time. Here's what really gets me. The pre-2007 trucks, the ones without AFM, they're bulletproof. I've got customers still daily driving them with 260,000 miles on the odometer. Not a problem in the world. GM took a perfectly good motor that would have lasted a lifetime and bolted this system onto it. And it is wrecking engines that should have run forever. The guys who hang around the forums already know all of this. So do the techs. They handled this years ago. They didn't sit around waiting for the dealership to mail them a warning letter, because that letter is never coming. It's the guys who figured somebody would've told them who end up on my lift. And I want to be clear, because this part matters. Maintenance has nothing to do with it. I've torn down motors with barely 30,000 miles on the clock. I pulled apart a Tahoe last summer with 24,000 on it. Practically a brand new truck. Owner had it less than a year. Spotless oil. Best synthetic money can buy, changed early every time. Made no difference. I've seen guys with full dealer records, every interval stamped. Made no difference. The oil changes were never the problem. The pin was. And no amount of babying that truck stops that pin from cycling every single time you drive. That's the part that eats at me. These are good motors. Take the AFM out of the equation and a 5.3 or a 6.2 will run 300,000 miles and never blink. So a few years ago I started telling every single owner who comes through my doors the exact same thing the smart guys already knew. Get yourself a FullForce disabler. It plugs right into the port under your dash. Couple of seconds and you're done. It just tells the computer to leave every cylinder running, full time. No more cycling. No more beating those lifters back and forth every time you turn the key. It doesn't reprogram anything. Doesn't touch your tune. And unplug it before a dealer visit and there's absolutely zero trace it was ever installed. I've had customers come back at 40,000, 60,000, 80,000 miles after I put one in. Zero issues. The trucks run smoother. And the lifters aren't getting beaten to death every single drive. I won't sit here and tell you it's magic. A lifter that's already damaged is a lifter that's already damaged, and this won't un-ring that bell. But it takes away the one thing causing all that wear in the first place. That's the whole game. You don't need a five-thousand-dollar delete. You don't need an expensive tune. You don't need to tear anything apart. You just need to stop the cycling. I'm not writing this for any company. I'm writing it because I'm tired of watching the guys who didn't know pay four and five figures for it. I'm tired of being the guy who has to break the news. I'm tired of knowing that the guys who did know fixed the whole thing for the price of a tank of gas, and the only difference was that somebody told them first. If you drive a Silverado, Sierra, Tahoe, Yukon, Suburban, or Escalade from 2007 or newer with a V6 or V8, you've got AFM. You've got those lifters, and they're cycling every single time you drive. So be the guy who already knew. Not the one I'm scraping metal out of next month. EDIT: A bunch of folks asked, so here it is. The one I put my faith in is FullForce. This is where to find it: https://www.tryfullforce.com/products/fullforce™-afm-dfm-disabler They back it with a 60-day guarantee too. I've handed out more than I can count and not one's ever come back to me. Not one. See less

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Thanks for following along. I'm not author material, my tenses are all over the place and an editor would have a heck of a time cleaning up after me. Reading and writing is still a fun pastime though.   My new scanner came in yesterday, wow, where the heck has this thing been?! It connects right up to the Blazer, there's all kinds of bidirectional tests like EGR activation and percentage, toggle the fuel pump relay, EVAP purge valve, IAC control, AC relay, reset the transmission's adaptive learning, toggle shift solenoids and TCC lockup, and I can reset fuel trims with the click of a button...all things I could have used over the last 60 days!   It's also telling me there is a stored code in the ABS module for front left wheel sensor open and something about the brake switch. The ABS dash light works. It illuminates normally during the self-test at key on/ start and that's it. I cleared the codes and will see if they set when I take it out later. That, and I'm going to get (hopefully) real data on timing and cam ******. The PID's are there.   I connected the tool to my truck...holy smokes. Newer vehicles make early OBDII vehicles look like 8-bit, pixelated, early Nintendo stuff. This? This is like wearing 3D virtual reality goggles playing one of those elaborate, cinematic video games with seasons and plots in comparison. There are SO MANY modules and SO MANY tests and SO MUCH data. There's a scanner sequence for filling the coolant...   End of the day, it's a tool with way more power than I need, but the versatility to do old and new is there (and I need an adapter to connect it to my OBDI Camaro). It will allow me to do the first pass of diagnosis when out-of-warranty vehicles need help, and it will enable more DIY maintenance like brake system bleeding, ABS bleed, etc. I probably over-bought here, but, mission is accomplished.   Enjoy your Sunday...I need to shut this machine down and go get ready for the week ahead.

      Which 2027 engine will you choose?

      Not that I've read, after all the issues they've had in the past I'm pretty sure they learned their lesson.
