Hello all, I have a 2007 Tahoe LTZ and am having strange electrical issues, just looking for some advice. Purchased used last year with 120,000 miles, wife was driving the other day and it had a no start in a parking lot. As I was headed to get her and look at it, she got it to crank. Since then it’s been in the yard with the following issues, all intermittent:
-no start
-instrument cluster working/dying at random
-slow power drain
-all warning lights like service 4wd, service tpm, etc on and off at random
-remote key/remote start intermittent
-intermittent radio and display blackout/no sound
-once while running and in park the transmission bucked like someone had bumped into the back at around 5-10 mph
I’ve checked grounds, fuses, the RKE module in the back D pillar, replaced battery, I’m leaning toward BCM or possibly the front air bag sensors, fairly sure one or both of those are bad. Could the airbag sensor cause a random laundry list of electrical issues or am I looking at one of these modules?
Thanks in advance for any advice!
