Hello, I noticed on my 2004 Chevy Silverado 2500hd 6.0 the brake lights were out. Looking further into it it’s only while the headlights are on and the truck is running, all is working fine while truck is off. As soon as I start the truck the brake lights work until I turn on the headlights, then they fade off like they loose power. The turn signals work fine either way and they are on the same led. I’m confused, I can’t find anything wrong. Thanks in advance!
I have a 2005 Tahoe 5.3 with 248,000 miles. On Monday morning I noticed that the cooling fan was running even though I hadn’t started the truck yet. Since then, the cooling fan will run after I turn the vehicle off. What’s odd is sometimes it won’t do it until an hour or 2 after it’s been off. Also my temperature gauge is fine, no overheating.
I did a code scan and P0480 comes up. I replaced the relay for cooling fan 1 and no change. I decided to disconnect the battery, cleaned the 2 huge harnesses that go to the PCM, and cleaned the connectors to the fan control fuse block (not sure if that’s the correct term sorry). I even removed and cleaned the connectors to the cooling fans and still no change. Could it be a grounding issue? I think I found the ground connector (passenger side radiator support area) but will have to put the truck on ramps to get a better look and grip on it. I’m kind of lost at this point and was wondering if anyone could help.
Hello, I’ve got a 2008 GMC Sierra SLT with z71 package. I’ve had it stock until this year (2020). Recently put a level it in and had the truck aligned and it ran great. Went to put new tires and rims which are 33x12.5 Toyo open country AT2 extremes on 18x9 fuel assault wheels. The truck obviously had a decrease in power and mpg but recently it has gotten significantly worse.
On HWY I can get 18-16 but recently in the city I am getting 11mpg!!! I live in a city with a lot of hills and windy driving so I can attribute that to some of it but it seems low.
I’ve looked around and some guys suggest checking air sensors and tune ups, but I am wondering at what point is it a bigger issue? Or is it the reality of a lifted truck with heavy tires?
any suggestions are welcome, it has not been 11mpg for long just the last month. Thanks
so I brought my truck in to get detail this past weekend. When I picked it up and drove maybe 50ft my doors locked and then kept constantly locking as if someone was pushing the lock button repeatedly. I took it back to the detailer and of course they claim they didn't do anything and they're not on the hook for fixing it. Has anyone had this issue before? I had a mechanic look at it and he said there is nothing wrong with the switches or door actuators. The truck is now at the dealer and I am hoping I dont have an astronomical bill to pay.

So I noticed in between the driver and rear seat of my 2017 Chevy Silverado 1500 LT underneath the truck was a harness hanging there. I looked up the part number to see what it's purpose was, because I couldn't find anywhere it plugged into. The part number is PBT-GF30. Can someone help me with this? Also my truck is idling in between 500rpm to a little over 1,000rpm when the truck is in park. I changed the intake air flow sensor but didn't do the trick.
