    Hey all, I'm new here but I've been fighting an electrical problem for a few days now on my new used 2011 Silverado Z71 (97k miles). At first I thought it was my daytime running lights on the driver side always staying on but upon inspecting it further it appears to be the turn signal lights...

    I changed the alternator, I put a different battery on, I clean and wire brushed and painted all the chassis grounds and when it was running I lightly tugged on battery cables and other wires and still can’t figure it out. It happens when I accelerate or if the radio is turned up also if I turn...

    A week ago I picked up a 2017 Silverado 1500 LT Z71 5.3 V8, with about 71k miles. Was running great for the first few days. A few nights ago, I let it warm up for a couple minutes and as soon as I put it in reverse I noticed it was idling rough and I got the traction control light and flashing...

    First post after scouring for an answer. Recently changed the plugs and wires in my 2013 Sierra 1500. After completion there was no fire going to the starter. Power would come on in the cab then when I went to crank, power was shut down. Did some troubleshooting and found the run/crank j-case...

    I am working on doing an engine swap in my 2010 Silverado. I am swapping in an 6.0 lq4 from a 2003 Silverado 2500 HD. Obviously, the two harnesses are not compatible. I figured I could merge the two harnesses together to get the truck running but I cant seem to find any wiring diagrams online...

    2010 silverado 1500. Non factory brake controller. I'm having an issue with towing a travel trailer. When my 7 pin is plugged in, I have a green light on my controller ( i interpret this to mean i have power to the controller). If I step on the brake, the green light goes out and the brakes...

    Bit of a weird one here, and hoping you guys can help. I have a 2003 Sierra 5.3L Automatic Z71 with 174K miles. The other day I went to start it up (it was already warmed up) and I noticed my radio, AC, door locks, windows, and all right gauges not working, nor the drive selection or 4WD...

    I have an '05 Sierra with a 5.3L. I have been chasing this issue for the longest time. I believe it is electrical but where I am not sure. When you put the key in the ignition, I try to turn it over. 7/10 times, it cranks first time no issue but the other 3/10 times, other things happen. Either...

    Are there fuses for the dash junction box that sits by the left foot of the driver. One of the wires had power to an after market radio and when undone and pulled through I stupidity allowed it to hit metal and it sparked for a second and now acts like it has no power. I can't find any fuses on...

    Hey guys I have a 2012 Sierra 2500hd which I got totaled from an auction and rebuilt a couple years ago. The past month and a half I’ll be driving and all my gauges go to zero except my battery one stays in place. When this happens the truck won’t shift out of first and the service traction...

    Howdy, brand new member and first post. I've been reading through the threads and had trouble finding an answer. Taking it into my own fingers; or however the saying goes. 2002 Silverado 1500 with 257000 on the clock and the 5.3 v8. For a long time had a very intermittent no power situation...

    So my window stopped working awhile ago, luckily all the way up. Thought it was maybe a crushed wire as i’ve dealt with that before. Couldnt see any damage. Checked voltage at connection to control module read 12v. Replaced control module but no dice. Figured maybe regulator/motor was dead, so i...
