Having the same problem with flasher noise like the blinker is on when not turned on. Blinkers and flashers all work normally. Tried new flasher under dash no luck. I guess will install new signal switch assembly
Clicking nose (like a blinker is on) even when my truck is off and no key in ignition. 2002 chevy av 1500. I've had a lot of issues but it's also really high in mileage at this point so I pay to fix it because I love this truck. Hoping this isn't a major expense.
noise from the dash, usually turn radio up to avoid having to hear it.
same problem but only in thr summer
