2003 GMC Savana 3500 Problems

Instrument Panel Lights Flickering and Exterior Lights Intermittent

The headlight switch used on the GMC Savana 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. 

Check Engine Light Due to Gas Cap Issue

A Loose or worn gas cap may cause Check Engine Light to illuminate.

2003 GMC Savana 3500 Recalls

Fuel Leak Due to Corrosion in Area Near Gas Cap

On vehicles equipped with a left side cargo door, water and road contaminants may become trapped in the protective conduit that covers the fuel filler pipe, which can cause the pipe to corrode. Significant corrosion may allow fuel to leak during refueling, and in the presence of an ignition source, this could cause a fire. Dealers will install a new fuel filler neck to correct this concern. The General Motors recall number is 12166.

Handicap Conversion Vehicles: Wheel Chairs Not Secure In Retractors

The retractor that secures a wheel chair in a handicapped conversion vehicle may be ineffective. Dealers will inspect and replace the wheel chair securement retractors as necessary to resolve the concern.
