Power Window System Components
The power window system consists of the following components
- LF power window master switch
- RF power window switch
- LR power window switch (4-door vehicles)
- RR power window switch (4-door vehicles)
- Window lockout switch (4-door vehicles)
- Window up and window down relays in each of the passenger window switches
- Reversible power window motors in each of the doors (circuit breaker protected)
- PWR WDO CB 25A (fuse block) (System power for left and right windows 2-door vehicles. System power for LF and LR windows 4-door vehicles)
- PWR WDO CB 25A (instrument panel (I/P) wiring harness junction block) (System power for RF and RR windows 4-door vehicles)
Power Window System Controls
The power window system will operate anytime the retained accessory power (RAP) system is active or when the ignition switch is in the ACCY or ON position.
The LF power window master switch can control the up and down functions of all the windows in the vehicle. The passenger door power window switches can only control the up and down functions of the individual window. The power window master switch also contains a lockout switch (4 door vehicles). The lockout switch controls the power window master switch lockout signal circuit. When the lockout switch is in the OFF position, the power window master switch lockout signal circuit is complete and the passenger door power window switches function normally. When the lockout switch is in the ON position, the power window master switch lockout signal circuit is interrupted and the passenger door window switches cannot control the up and down functions of the power windows.
Rear Window Defogger System Components
The rear window defogger system consist of the following components
- HVAC control module
- Body control module (BCM)
- DEFOG relay
- Rear window defogger grid
