GMC Sierra 3500 ProblemsInstrument Panel Lights Flickering and Exterior Lights Intermittent
The headlight switch used on the GMC Sierra 3500 is known to fail through normal operation. Since the headlight switch is also integrated into the interior lights, a malfunctioning switch can cause issues with interior lights as well.
- Symptoms of a failed headlight switch include:
- Headlights and taillights failing to turn on or off
- Interior lights flicker, or fail to turn on or off
- Gauge cluster lighting off or flickering with headlights on
- Parking light malfunctions
This issue is well known with General Motors Trucks and SUVs, and is solved by testing and, if needed, replacing the headlight/dimmer switch. Bad grounding wires at the tail-lights, and dirty/corroded tow package wires can also lead to some of these issues.
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.

GMC Sierra 3500 RecallsFront Passenger Air Bag Defective
In a crash that deploys the passenger front air bag, the inflator of the air bag can rupture, causing metal debris to strike vehicle occupants. Dealers will replace the front passenger air bag inflator free of charge to correct the concern.
If too much current is drawn from the auxiliary battery, the fusible link can melt, causing risk of fire. Dealers will replace the jumper harness with one that includes a 40 amp inline fuse, and provide vehicle owners with supplemental owners manual information free of charge to resolve the problem.
The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire. This previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.
