Blower doesn't change speeds, always on low.
GM_Chris posted a question in Ask the GM TechnicianNeed Help badly... 2013 GMC SIERRA 2500HD. Blower doesn't change speeds no matter dial setting. Speed is like its on low. Blower seems to almost stop when selecting max ac recirculation button. Please help. Thanks in advance.
Hello guys & lady mechanics, I’m in the process of replacing my rear disc brakes, it has 4Wheel anti loc disc brakes. I have the rear rotors with the interior surface for the parking brake shoes. I have new rear backing plates and hardware. But I noticed a little bit of a runout in the axles, I’m assuming it’s normal bearing wear. It has 175,000 miles on it. Plus the brake lines rusted and caused a pedal to the floor issue for me, so I replaced every single brake line with all new stainless steel lines, and new brake hoses. It has new rotors and pads upfront. What I’m trying to find out, since it’s a 14 Bolt GM differential in the rear, what exactly do I have??? 1) Is it a 9 1/2 inch ring gear, 14 bolt rear end, or is it a 10 1/2 inch ring gear 14 bolt rear end? Where can I find this out. I need to order bearings and seals, and a pinion seal which is leaking. which is my next question, 2) how do I determine what size my pinion seal is before I order one? O’Reilly shows 8 options 3) Last question is, I’m assuming I’m going to have to pull the cover, remove the locking pin for the limited slip differential, and push the axle in, pull the retaining clip, and pull the entire axle out to get to the seals and bearings, correct? My plan is to put a new B&M aluminum differential cover and fresh fluid once this is all done… Lastly I wish I would’ve found this side or search prior to doing my brakes, I would’ve found out that GM was offering half off To replace all new brake lines for $500. It’s done now though. Happy holidays you’ll Dave
06 gmc 2500 rough idle
Jacks1821 posted a question in Ask the GM TechnicianSo I got a 2006 gmc 2500hd with the 6.0 vortec. The truck idles really really rough. Like it almost dies when it’s up to temp and in park or at a stop and It makes a loping sound. The weird thing is, it drives fine once you give it some gas. I’ve replaced the throttle body itself, replaced the TPS, replaced the mass airflow sensor, I’ve even changed the air filter itself. I’ve checked the spark plugs but those are fine. I’ll also note that I replaced the intake manifold gaskets because those were pretty bad. I’m really not sure what else it could be because like I’ve said, once you give it some gas and start to go it runs perfect but as soon as you come to a stop it almost dies. Any help is appreciated.
Help ! At our wits end !
MeanGreen01 posted a topic in 2000-2014 Silverado & Sierra HDHello ! I have a 2001 Silverado 1500 HD 6.0 the truck started running rough out out of the blue and is showing a code for cylinder 2 &7. We have replaced Plugs, Wires, Coil Packs, fuel regulator & fuel pump. injectors have been checkd and thats not a problem either. We are still only getting 45 pounds of pressure With everything replaced. What else could it be ?!
So I have a Sierra 2500HD with the 6.0 and apparently 4.10 gears. 2 wheel drive. I know that may have been an option that year, but it does seem possible as the only upgrades on the truck are AC, Cruise, and tow package. Someone must have bought for pulling. Anyway we put a dump bed on it and use it as a chipper truck in our tree service. Even when we try to fill it half full and pull the chipper, we could use more torque. (I AM FULLY AWARE THAT WE NEED TO UPGRADE TO A BIG FRAME TRUCK!) but in the mean time, I've got to make this work. Would you guys go to 4.56, 4.88 or all the way to 5.13? I know highway cruising will be a thing of the past but I really need to focus on towing and taking a load off that automatic tranny. I assume when we sell the truck the next owner will be interested in the same thing with it being a light duty dump truck. Some stats on the truck are: 8 foot flat bed with the custom removable sides, top cowl, and rear tail gate probably weighs around 1500lbs alone. 5 ton hoist kit has been flawless, and dumped everything we've ever loaded it with, even though we changed the pivot point to dump higher than 45 degrees, slightly lowering its capacity. Air lift/air bag helpers with compressor kit so we can keep it full when heavy and low when empty. Doing a light tree job 1/2 day, we put about 2000lbs of chips in it, and tow another 3000-4000 in equipment. On my worst day we dumped 5,500lbs and I felt like a super idiot when we weighed in.
