Q: What Should You Do If Turn Signal and Hazard Flasher Function Fails on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?
A: The turn signal and hazard flasher relay on certain vehicles is handled by the Body Control Module (BCM). If a bulb on one side of the vehicle flashes faster than normal while the other bulb on the same side doesn't light up, it's likely that the non-flashing bulb is faulty and needs to be replaced. If none are flashing, replace the Body Control Module.
