- Verify if power (B+) was lost during window operation.
Was power (B+) lost while the window was in operation?
- Yes: RAISE the suspect window to the fully closed position. VERIFY the window glass stalls into the upper header seal for 2 seconds and release the switch. LOWER the suspect window to the fully open position. VERIFY the window glass stalls at bottom of travel for 2 seconds and release the switch. The window should function normally.
- No: For LH front window, GO to 2
.
For RH front window, GO to 4.
- INITIALIZE THE WINDOW MOTOR
- Carry out the window motor initialization procedure. REFER to Window Motor Initialization .
Is the one-touch up/down feature operating correctly?

-
NOTE: Voltage should be present on both circuits in each of the tested switch positions.
While pressing and holding the LH front window control switch in both the UP and DOWN positions, measure:
LH Front Window Motor Ground C524 Ground Pin Circuit Measurement / Action Pin Circuit 4 CPW11 (BU/GY) - Ground 5 CPW10 (YE/OG) - Ground
Are the voltages greater than 11 volts when the window control switch is fully pressed in UP and DOWN positions?
- Yes: INSTALL a new window regulator motor. REFER to Window Regulator Motor - Front Door . INITIALIZE the window motor. REFER to Window Motor Initialization .
- No: INSTALL a new LH front window control switch. REFER to Window Control Switch .
- INITIALIZE THE WINDOW MOTOR
- Carry out the window motor initialization procedure. REFER to Window Motor Initialization .
- Verify the RH window operation from the LH and RH front window control switches.
Does the one-touch up/down feature operate from both the LH and RH front window control switches?
- Yes: The system is operating normally at this time. The window motor lost initialization.
- No: If the one-touch up/down feature is inoperative from only one switch, INSTALL a new window control switch. REFER to Window Control Switch .
If the one-touch up/down feature is inoperative from both switches, INSTALL a new window regulator motor. REFER to Window Regulator Motor - Front Door . INITIALIZE the window motor. REFER to Window Motor Initialization .
