New to Me 2010 SLE (Quirks, Issues)

First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.  

 

Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.  

 

Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue. 

 

Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.

 

Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.

 

Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.

 

Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.

 

Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.

 

Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.

 

While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.  

 

For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

Thanks!  I think the batteries may be shot.  The relearn process is pretty simple: ignition on, hold the lock and unlock buttons on the RKE for a few seconds, and the horn beeps twice to denote learning mode.  I tried the 10 second deflate trick and just tried the TPMS learning tool I ordered last week.  Nothing.

Well, before I bought new TPMS sensors I'd test  the batteries, or the heck with it; just put new sensors in with KNOW GOOD BATTERIES, dont just trust batteries just because they are new to you.

You can't change the batteries in TPMS sensors.  You have to replace the sensor.

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

      By Atlas · Posted

      While waiting for parts I have been working on installing the AC compressor, new accumulator, and orifice tube. Also changed out the high side ball valve (original). The orifice tube that was in there wasn't too bad. Slightly dirty, a little bit of junk, but not blocked. Glad I changed it out.   The accumulator, which should have been a 5 minute job, may have just burned $50. Put some PAG in it, wrote the date and mileage on the side, fresh o-rings and gooey'd up the threads and rings with Nylog. Got everything connected and snugged and was going to vacuum down the system, and....   My manifold gauge won't fit on the port. It's not an R12 service port. It LOOKS like an R134 service port but the diameter is a hair too large. There's a sticker on the accumulator that says it's designed to be used with R12 and R134a systems only. So it's not R1234yf. Even if I reduced the diameter slightly with a file, the shoulder on the port is too large so the quick-connect valve won't lock on. I'm stumped. It's going back, and 50/50 on if they'll give me a refund.   Also, I did a fuel pressure test.... Key on, the gauge spikes to about 60psi and quickly bleeds off, like 2psi per second. The fuel isn't going into the plenum, no smell, starts fine, so I'm guessing there's a bad check valve in the pump and the fuel is just draining back into the tank. oh, hell. But, it shouldn't be a problem, pump primes just fine and the truck starts right up. It just means I can't really ever use fuel pressure to verify a leak at the injector or intake.

      SERCICE ESC message?

      By No F-bdy Bs · Posted

      Got this yesterday out of nowhere. Truck is a 25',6.6 gasser with 8k miles.  Only semi anomaly is that the truck had been sitting, uncranked for 6 days. Elec Stability Control showed immediately upon cranking, not while driving. No drivability issues, just the message. Battery didn't seem to be weak when cranking over.  I drove it, killed it, let it sit a few hrs with no avail.  Truck is 100% stock. No damage.

      on-wheel cellphone control: 2026 1500 WT (2.7L 4WD std cab)

      This can be done.  It is not cheap and requires an instrument cluster swap with custom programming, new steering wheel with the controls on it, and a special jumper harness.   The cluster upgrade - 12.3” Digital Cluster Upgrade – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The wheel upgrade - Steering Wheel Upgrade Kit – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The column harness upgrade - 2019 - 2026 Silverado / Sierra: Steering Wheel LIN Bus Harness - Harness Dr. - DIY Done Right     The problem with doing all of this?  You pretty much can't have any programming done to your truck that involves the cluster ever again.  The dealer won't be able to program the cluster as GM's system will only pull data for the cluster the truck came with.  So it would be advised also to turn off over the air updates.   TLDR;  Should have bought an LT double cab?  You'd have a power seat, the wheel controls, the cluster, all things that you've been seeking in your various posts so far about your new WT regular cab.

      2026 TurboMax L3B 2.7L: AFM/DFM present/disablable? [2026 Silverado 1500WT: 4WD RC RB 2.7L]3GCNKAEK9TG345558

      By newdude · Posted

      Yes.  The 2.7 Turbomax has Active Fuel Management.  It is NOT the same as the V8s.  Totally different system.     Here is an article from GM when the 2.7 came out explaining the cylinder deactivation and the valve lift system.  Starts at the section called "SCS Valvetrain":   New Turbocharged 2.7L 4-Cylinder Engine Powers Full-Size Trucks – TechLink         This is an internet myth going around.  It was alleged that some 5.3s had this mystical 8th digit of the VIN as an "E" which somehow meant it had a new one year only 5.3 that didn't have DFM.  The writer of said article and the person that made the claim conveniently can't count because they posted the VIN.  The 8th digit was a "D" which meant its still the 5.3 with DFM.  The 9th digit of the VIN was an "E" and the 9th digit isn't the engine code.  At all.
