2002 GMC Safari ProblemsInstrument Panel Lights Flickering and Exterior Lights Intermittent
The headlight switch used on the GMC Safari 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 power door locks may stop working in one or more doors due to a failed actuator. Replacement of the failed actuator should correct this concern.
The outside door handles are prone to breaking—all doors are affected by this condition.

Can jump the negative wire and compressor starts. But can't leave the jump as it would drain power when off..
I've heard there has been problems with wiring harness corroding and wires breaking. Do I need whole harness replaced? CPU?
