GMC Sierra owners have reported 3 problems related to headlight switch (under the exterior lighting category). The most recently reported issues are listed below.
Headlights have been adjusted by the dealer twice. The headlights are a single bulb design (low and high beams from one bulb). If low beams are adjusted to adequately see the road during night driving the high beams point into the air (approx. 10 feet in the air at 100 feet from the vehicle). If the beams are adjusted to allow the high beams to illuminate the road properly; when switched to the low beams there is insufficient light on road to drive safely at 55 mph.

Headlamp light switch works on and off, making it hard to drive at night. The lights would go out while the vehicle was in motion. The unit required that the turn signal had to be replaced.

Both hi and low beams of headlights went out while driving vehicle at night. Went to dealer next day. Dealer charged $502. 65 to replace headlight dimmer switch. Wiring was melted and burned on switch. This could have started a vehicle fire, or caused an accident. Fuses and circuit breakers did not protect vehicle wiring. Switch is available if you would like it for examination.
