2007-2014 GMC Sierra: Why do my speakers only work sometimes?

Sun, 16 Jul 2023 14:10:43 -0700

My truck’s passenger speaker has been going in and out. Today however, my drivers side has gone out as well. My rear speakers have never worked. I don’t know if it is a speaker issue or if it is a wiring issue. Any ideas?

2007-2014 GMC Sierra: My drivers window doesn’t roll down or up. The switch just buzzes

Fri, 23 Aug 2024 21:43:37 -0700

Window doesn’t roll up or down the window button just buzzes when trying to use the window controls. I was having issues with the passenger window also. I replaced the switch panel and that fixed the passenger window but the drivers window still buzzes and won’t move.

2007-2014 GMC Sierra: Why does my car stereo speakers surge when I press the brake?

Fri, 21 Jan 2022 01:23:57 -0700

When I press the brake, there is a surge/thump that hits the speakers. At other times, my warning lights on my dash all blink, my radio’s time changes, and my door lock will flip up and down several times. I had my alternator and driver side window control panel replaced but nothing seems to help. Any ideas?

2007-2014 GMC Sierra: Limp mode, p1682 “Driver 5 Line 2” cel code

Tue, 09 Dec 2025 21:07:41 -0700

Truck has been driving rough the past month to 2 months. Ran a code reader to find out 8-10 codes popped up and 70% of those codes were O2 related (this truck does have an exhaust leak on the driver cat). The other 30% of codes (some codes go away and pop right back up) was the p1682 I mentioned in the title, faulty maf code (removed and clean sensor) and misfire but just recently replaced plugs/wires and double checked everything.

So It seems I can drive the truck so far then eventually it will kick into limp (no acceleration and tachometer revs rapidly while engine shakes aggressively) mode leaving me stranded unless I replace a 15amp ecu/trans fuse and reset the computer via battery terminal. The battery that’s in the vehicle isn’t the correct oem rated cca, (615 cca) instead it’s a much higher cca (690+) and reserve minutes.

Would that cause a issue with lack of power/blown fuses? Has anyone experienced/experiencing these issues? Purchased the truck 5 months ago and don’t want to get rid of it but its giving me a headache honestly for someone thats mechanically inclined, I realized I really don’t know much past a intermediate level knowledge of vehicles.

the engine size is the 4.3L 6 cylinder motor

2007-2014 GMC Sierra: No Title (You should edit this question)

Sat, 28 Sep 2024 04:06:02 -0700

I have a 2017 sierra 1500 and it won't crank or turn over SOMETIMES. Originally I went and got my battery/alternator/starter tested at O'Reilly's because sometimes it wasn't starting. Starter tested bad so I replaced it. Ran great for a few days and then wouldn't start. Went back and got it retested and it was also a bad battery, replaced it. Ran again for a couple days and did the same thing. I've replaced additionally the starter 40 fuse, ECM relay, run/crank relay, starter relay that were all under the hood, ignition switch and the anti theft fuse in the driver side panel. For a while I thought maybe it had to do with disconnecting the battery. Every time I'd disconnect it when it wasn't starting, it would start if I let it sit for a couple hours with the negative cable off. I got it in my head that maybe it was resetting a system like the anti theft or something. It still does this thing where it runs great for a few days and then won't start. I'm at a loss and no mechanic around here has a clue. Help!
