Normal Operation
NOTE: Circuits 884 (YE/BK) and 885 (YE/LB) change to 881 (BN) and 882 (BN/YE) in the LR door jumper harness.
Under normal operation the rear window control switches receive power from the front window control switch through circuit 170 (RD/LB) when the LOCK OUT feature is not active.
When the rear windows are operated using the front window control switch to the UP position, power is sent through circuit 317 (GY/OG) for LR/319 (YE/BK) for RR and ground through 316 (YE/LB) for LR/320 (RD/BK) for RR. When the rear windows are operated using the front window control switch to the DOWN position, power is sent through circuit 316 (YE/LB) for LR/320 (RD/BK) for RR and ground through 317 (GY/OG) for LR/319 (YE/BK) for RR.
When the rear windows are operated using the rear window control switch to the UP position power is sent to the rear window motor through circuit 884 (YE/BK) LR/881 (BN) for RR and ground through 885 (YE/LB) for LR/882 (BN/YE) for RR. When the rear windows are operated using the rear window control switch to the DOWN position power is sent to the rear window motor through circuit 885 (YE/LB) for LR/882 (BN/YE) for RR and ground through 884 (YE/BK) for LR/881 (BN) for RR.
Possible Causes
- Inoperative front window control switch.
- Inoperative rear window motor.
- Inoperative rear window control switch.
- Open in circuits 170 (RD/LB), 316 (YE/LB), 317 (GY/OG), 319 (YE/BK), 320 (RD/BK), 881 (BN), 882 (BN/YE), 884 (YE/BK), OR 885 (YE/LB).
