2006 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.

Some vehicles have a power steering hose that was not made to specification and may rupture under extreme steering conditions. If this were to happen, power steering assist would be lost and steering effort would increase. On vehicles equipped with hydro-boost brakes, braking effort would also increase. If power steering fluid were to spray on hot engine parts, an engine compartment fire could also occur. Dealers will inspect the power steering hose(s) for the two suspect date codes and replace them if needed. The recall began October 14, 2005. The GM recall number is 05086.
