Pinpoint Test
- CHECK FOR POWER (B+) LOSS DURING WINDOW OPERATION
- 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 Left Hand (LH) front window, GO to step 2
.
For Right Hand (RH) front window, GO to step 4 .
- Verify if power (B+) was lost during window operation.
- 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?
- Yes: The system is operating normally at this time. The window motor lost initialization.
- No: GO to step 3 .
- Carry out the window motor initialization procedure. REFER to WINDOW MOTOR INITIALIZATION .
- CHECK THE Left Hand (LH) FRONT WINDOW CONTROL SWITCH OPERATION AT THE WINDOW MOTOR
- Ignition OFF.
- Disconnect: Left Hand (LH) Front Window Motor.
- Ignition ON.
- While pressing and holding the Left Hand (LH) front window control switch in both the UP and DOWN positions, measure:
- 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 Left Hand (LH) front window control switch. REFER to WINDOW CONTROL SWITCH .
NOTE: Voltage should be present on both circuits in each of the tested switch positions.Courtesy of FORD MOTOR CO.
- INITIALIZE THE WINDOW MOTOR
- Carry out the window motor initialization procedure. REFER to WINDOW MOTOR INITIALIZATION .
- Verify the Right Hand (RH) window operation from the Left Hand (LH) and Right Hand (RH) front window control switches.
- Does the one-touch up/down feature operate from both the Left Hand (LH) and Right Hand (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 .
