Step 5 - 8:

Normal Operation
The LH rear window control switch receives power from the accessory delay relay through circuit (R/LB). The LH rear window control switch provides power to the LH rear window motor through circuit (Y/B) and ground through circuit (Y/LB) to operate the LH rear window DOWN; and power through circuit (Y/LB) and ground through circuit (Y/B) to operate the LH rear window UP.

When operating the LH rear window using the driver window control switch, power is sent to the LH rear window control switch through circuit (R/B) and ground through circuit (Y/B) to operate the LH rear window DOWN; and power through circuit (Y/B) and ground through circuit (R/B) to operate the LH rear window UP.

Possible Causes
- circuit (R/LB) open
- circuit (Y/LB) open or short to ground
- circuit (GY/O) open or short to ground
