Has anyone had any issues with their 08 silverado 1500 shorting out? I don't know if its a short, ground issue or a bad body control module. My issue only happens when I am driving over 60mph. Intermittently when hitting the blinkers or the brakes the electrical system freaks out. Gauges start going crazy, radio goes out, door locks lock and unlock over and over, airbag light comes on, abs light. Seems to be happening more and more frequently. The other day it through it into 4 low and totally died on me. Took positive lead off battery put back on fired up with no problems. I just don't want to spend money on one thing and it not being that then another and another. Wondering if anyone knows what this could be. I have no aftermarket electronics. I recorded it happening and put it on YouTube. Here is the video link
Howdy, totally new here with a problem. We have a 2007 Tahoe LTZ that developed an issue about a month ago. My wife is for the most part the only driver and weve had it since new. Since she retired she drives it about 1000 miles per year, mostly full of grandkids. About a month ago it started flashing "traction control off, service stabilitrak. It turned on a cel : p0101 lost communication with tcm. Shortly after the rear hatch wouldn't open, the shift indicator quit working, and it picked up a p0073 code. The next day it wouldnt start, showing a security icon. I disconnected the battery and reconnected it after 1/2 hour, it restarted, the security icon was off, I backed it into the shop, shut it down, restarted it with my scanner hooked up checked fuses, wiring for damage etc. It was on reduced power with the same codes, battery @ 12.6v shut off 13.8v @ idle the it died, the security icon was back. I disconnected the battery again, this time overnight, now it still has the security icon, wont crank or start and it wont communicate with my scanner. Im leaning toward the ecu as we had a similar issue with our Ford Powestroke a few years ago. I dont want to throw parts at this but Im kind of up against a wall at this point. Any suggestions would be appreciated! I have a 53 m38a1 with a Kubota turbo diesel SM465 and less electronics than her stereo. My suggestion was to build something like that. Shes not interested. Thanks again!
