Test A: A Single Power Window Is Inoperative - LF
PINPOINT TEST A: A SINGLE POWER WINDOW IS INOPERATIVE - LFNormal Operation
Under normal operation, the LF power window motor microprocessor receives power at all times through circuit SBP01 (RD) and from the accessory delay relay through circuit CBP41 (BU). Ground is provided at all times through circuit GD143 (BK/VT). The master window control switch provides voltage input to the power window motor microprocessor through circuit CPW10 (YE/VT) to operate the driver window down, and voltage input through circuit CPW11 (BU/GY) to operate the driver window up.
This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- Window control switch
- Front door window regulator motor
