Hi guys, just looking for some advice. The issue: I recently had my battery replaced and shortly after this was done my low beams (both sides) quit working. The next day my stereo started turning off and on again, and there's a message on the dash saying "service theft deterrent system" with the lock symbol. I can still drive it though (not at night) and it doesn't lock me out. I checked the fuses and relay for the low beams and they seem fine. I haven't checked the bulbs yet but it seems too coincidental that both would go out at the same time, though I could be wrong. In case this is relevant info: I had the battery replaced a month ago via AAA, but it turned out to be from a bad batch. It died after a few weeks while I was conveniently at a local shop getting a wheel alignment, so the mechanic there jumped it twice (once to get it onto the rack and another to get it back in the parking lot). They showed me how the interior lights were flickering before shutting it off (I didn't see the headlights at that point). AAA replaced the battery in the lot after that since it was under warranty. Any suggestions would be appreciated. I'll take it to a mechanic next week but I wanted to do some research first to see if there's an easy fix I may have missed. Truck is a 2011 GMC Sierra 1500 SLE. Thanks! Caitlin -
I’m looking for a service manual, the folks who had my truck before me didn’t some pretty crappy wiring, and just seeing if anyone has a online service manual for these trucks. I’ve got to get some stuff fixed on it and don’t plan on paying my old company to fix my truck. Thanks for everything. -
I have a 2011 Sierra SLT 1500 Extended Cab, I have rear parking sensors and back up camera which displays in my rear view mirror. I was in an accident and a lot of my front end is being replaced, (bumper, grill, etc). Since I already have rear parking sensors I was curious to know how difficult and expensive it would be, if it’s even practical, to install parking sensors on the front as well. Any input would be great! Thanks! -
So this one is a little complicated I drive a 2011 GMC sierra denali, it has the 6.2L V8 with long tube headers and cold air intake. It has also been tuned trying to fix the issue with no luck. While driving about 30-40 mph it begins to buck or lag like the truck is misfiring but there are no codes and i dont believe it is actually misfiring. it seems to struggle unless i am on the gas constantly. It has a similar issue when in the 50-60 mph range as well. Any other time the truck seems to run fine. The best way to describe the anomaly is it seems to oscillate almost for the time it does this instead of smooth acceleration or smooth cruising. It isnt the tac either, it can be heard in the exhaust that it is not running smooth. The things i have done chasing the problem: New injectors, new spark plugs, oil catch can, new spark plug wires, tune, replaced transfer case, cleaned throttle body, new throttle position sensor, new crank shaft position sensor, cleaned all grounds, new MAF, new MAP, new o2 sensors, new air intake manifold. I am starting to think this truck will never be fixed. HELP WANTED lol Thank you for your time.
