Hey Al,
New to the site
I’m looking for some insight on my 07 Tahoe LT weird stuff going on
I am having all sorts of lighting and random issues. First my low beam head lights do no come on. I then swapped the relay with another relay for the headlights no change. I then inspected both 20amp fuses good. I’ve replaced the fuse block under hood and headlight switch. No change. High beams do work when commanded on. I removed the fuse block and tested both LF and RF low beam circuits at under hood box with a power probe commanding them on with power. They did in fact came on and both worked. I then went to the BCM found the ground control at BCM with under hood fuse block on headlight switch on and snipped the wire and manually grounded it. Again headlights did not come on. I’m kinda at a loss.
Now with the truck off key out of the ignition the RR Lower stop light bulb and running bulb are stuck on. So again went to bcm and simply unplugged the brown connector that grounds it lights DID NOT go out. I then removed the brand new 500 fuse block and the light went out. So again scratching my head.
I also have have a wierd issue where the airbag light will come on and go off. I tried scanning it for code with a tech 2 and no communication with the module.
Lastly the left side turn signal in the rear will not flash. I checked the bulb bulb was indeed good. I checked the tail light harness with a the power probe light indeed it is good.
Any insight would be greatly appreciated. I do have access to GM global connect for wire. Diagrams and diagnosis with again no luck.
Thank you all
