Q: How to replace a headlight bulb on a Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?
A: If you're replacing a right-side bulb on a truck model, remove the air filter housing. If you're working on an SUV model, remove the Headlight housing. Disconnect the headlight bulb electrical connector, rotate the bulb holder counterclockwise, and remove it from the housing. Installation is the reverse of removal.
