Runs and drives great. Problem is I can't use my turn signals. When I use them I lose all dash lights and gauges. Everything else works great. Power likes, power doors, security etc. I was told possibly a bcm but when I called the dealership they said it was $700 and isn't guaranteed to fix the issue. We tried removing the fuse box and cleaned that all down from corrosion and that fixed the issue for a ride to town. On the way home it happened again as soon as I hit the turn signal to turn. Lost all lights and gauges again! Please help!
Check for a bad ground wire for the dash circuits
Testimonial: "Ok where would that be? I know we have also tried doing the reset on the dash as well and that did nothing! Disconnected the battery too and nothing."
disconnecting the battery causes more problems that it fixes as it corrupts the CPU program in the ECM as for the ground wire , it will be a black wire under a bolt head or screw
A workshop manual with an electrical schematics would be a big help or talk to an auto electrician with experience on your make of vehicle
