2006 GMC Savana 1500 Problems

Instrument Panel Lights Flickering and Exterior Lights Intermittent

The headlight switch used on the GMC Savana 1500 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. 

"No start" Caused By Failed Fuel Pump

The fuel pump may fail causing the engine to stall and not restart.

Replace spark plugs every 100,000 miles

The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.
