WIRING DIAGRAM
INSPECTION PROCEDURE
| 1.INSPECT POWER WINDOW REGULATOR SWITCH ASSEMBLY |
Remove the power window regulator switch assembly ().
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Switch Condition | Specified Condition |
| 4 (U) - 3 (B) | UP | Below 1 Ω |
| 2 (SD) - 1 (D) |
| 5 (SU) - 4 (U) | OFF | Below 1 Ω |
| 2 (SD) - 1 (D) |
| 5 (SU) - 4 (U) | DOWN | Below 1 Ω |
| 3 (B) - 1 (D) |
| | REPLACE POWER WINDOW REGULATOR SWITCH ASSEMBLY ()
|
|
|
| 2.INSPECT FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY |
Remove the front passenger side power window regulator motor assembly ().
Apply battery voltage to the motor connector according to the table below.
