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?

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.
