2003 Cadillac Escalade EXT Problems

Instrument Panel Lights Flickering and Exterior Lights Intermittent

The headlight switch used on the Cadillac Escalade EXT and ESV 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. 

The Fuel Pump May Fail Causing the Engine to Stall or Crank Over But Not Start

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

We have problems with navigation system and heater control on passenger side. Dealer can't duplicate the problem and doesn't want to swap a bunch of unnecessary parts.
