For 1990-2009 cars only
- Inspect the power windows circuit breaker.
- If only the left front power window switch operates the windows, ensure that the lockout switch is not engaged.
- Verify that ground G301 is clean and tight.
- If a motor's internal circuit breaker trips, the circuit breaker will not reset until voltage is removed from the motor.
- Refer to repair procedures in order to access the power window system.
- Inspect for a broken (or partially broken) wire inside of the insulation.
- Inspect for proper installation of the aftermarket electronic equipment.
A broken wire inside of the insulation may cause a system failure but prove good in a continuity/voltage test.
Improper installation of aftermarket electronic equipment affects the integrity of other systems.
