Power Windows System Components
The power window system consists of the following components:
| • | LF window switch |
| • | RF window switch |
| • | LR window switch |
| • | RR window switch |
| • | Window regulator motors in each of the doors |
| • | System circuit breaker (Power Wdws Circuit Breaker 30A) |
Power Windows System Controls
The power windows system can be controlled by a power window up or down switch activation
LF Window Operation
When the ignition switch is in the RUN or ACCY position, or Retained Accessory Power (RAP) is enabled and the LF window switch is pressed in the down position, battery positive voltage is applied to the window regulator motor causing the window to open. When the LF window switch is pressed in the up position, voltage is applied to the window regulator motor in the opposite direction and the window closes.
The LF window switch also controls the RF, LR, and RR windows.
Express Down Feature
The LF window will travel to the fully down position when the LF window switch is pressed past the first detent. Pressing the LF window switch to the up position will cancel the express down feature.
Lockout Switch Feature
The LF window switch has a lockout switch which disconnects the battery positive voltage to the LR and RR window switches, disabling them.
Individual Window Operation
When the ignition switch is in the RUN or ACCY position, or Retained Accessory Power (RAP) is enabled and an individual window switch is pressed in the down position, battery positive voltage is applied to the window regulator motor causing that window to open. When the individual window switch is pressed in the up position, voltage is applied to the window regulator motor in the opposite direction causing that window to close.
