2003 Cadillac Escalade EXT ProblemsInstrument 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 and not restart.
A Loose or worn gas cap may cause Check Engine Light to illuminate.
