For about a year now I've been battling with what I'm guessing is an electrical issue. I'm driving a 2015 Chevy LML. (Tuned, CP3 conversion, Airdog system). All my gauges will start going crazy along with the cluster lighting up like a Christmas tree. I'll get ABS warnings, trailer brake warnings, and stabilatrak warnings. Then my transmission will start downshifting and upshifting, and when changing gears it changes really hard, shaking the truck. It happens randomly. I did figure out though that whenever I turn my AC on, this weirdness happens immediately. Any ideas? I've spoken with multiple mechanics, and they said without a Check Engine Light they don't know where to start looking. One mechanic rode with me and saw what it was doing and tried to read the codes. It threw TONS of codes, and he didn't know where to start. It was throwing lots of BCM and ECM codes. I feel like cutting my losses and just dropping the truck off at the scrap yard. I can't afford to spend tons of money hunting for a problem we may never find.
I'm thinking to start with taking out all of the AC components and put new ones in. What do yall think? I'd hate to take it any further.
