    2012 GMC Sierra Electrical Issues. NEED HELP!!

    It's not a new truck. 2012. I'm giving it one last shot and going to get under the dash and see if I can't get some leeway from that end. Maybe tidy everything up a little better. I don't want to do something halfway. If I can't get it by then, it will have to go into the doc. Thanks for all of...

    2012 GMC Sierra Electrical Issues. NEED HELP!!

    I will get you a picture in just a bit. The reason why I said "bonnet" is because there is this black think covering all the wires. If there is a grommet it's the strongest one I have ever seen. I can't push it in or out!

    2012 GMC Sierra Electrical Issues. NEED HELP!!

    I am having a lot of issues getting the "bonnet" off of the main wiring harness. I am thinking about cutting it away to be able to get to the wires and them taping it back up securely. Any help/advice would be appreciated.

    2012 GMC Sierra Electrical Issues. NEED HELP!!

    I am having a serious mechanical/electrical problem and I really am at a loss of where to go. I pretty much tore my truck apart to put new carpet and utility lighting throughout. In doing so, I was trying to go through the main grommet in the firewall with an exacto and it must have hit...

    Torn rear step pad on bumper

    A while back I backed over something and it tore the step pad under my rear bumper on my left side. No other damage was done. But I can't for the life of me figure out how to fix it without buying another one (and I don't want to do that). I've tried plastic welding and I just can't get a good...

    Need AC help, compressor still working

    I am having some trouble getting my AC to cool. Checked the freon and looked like it needed a bit, but when I put only a tiny bit in, the psi went completely into danger zone. The compressor seems to be kicking on fine. When I get up to around 60mph, it cools off more, but today only to 70...

    Need help with an aftermarket glasspack fitment

    First off, thank you so much for your advice. What do you think about the dynomax 17797 super turbo? I can get a great deal on it and it checks all the boxes. Let me know any opinions.

    Need help with an aftermarket glasspack fitment

    The problem I'm having is that any 3" adapters, whether they are OD or ID aren't fitting around or in the glasspack I have. Am I looking at expanding the pipe a bit? Any suggestions on getting the adapters to fit?

    Need help with an aftermarket glasspack fitment

    Unfortunately, that's the problem I'm finding is that it's not an easy in/out situation with the adapters. The closest I can get leaves about a 1/16" gap. Everything is so expensive in the Austin TX area and everyone wants to overcharge here. Any ideas on how to narrow the gap?

    Need help with an aftermarket glasspack fitment

    I have a 2012 GMC Sierra 1500 with 2.75" exhaust pipe. I am wanting to delete my muffler and add a glasspack without welding. Problem is, I can't find any adapters to fit anything. Do I go with a 3" or a 2.5" glasspack? And whichever one I go with, what size adapters/reducers do I use? The...
