Component Testing

Master Window Switch 

1. Ignition OFF, disconnect the X1 and X2 harness connectors at the master window switch.
2. Test for less than 2 ohms between the control terminal 4 and the ignition terminal 1 with the lockout switch in the ENABLE position.
   • If greater than the specified range, replace the master window switch.
3. Test for infinite resistance between the control terminal 4 and the ignition terminal 1 with the lockout switch in the DISABLE position.
   • If less than the specified value, replace the master window switch.
4. With the switches in the INACTIVE position, test for infinite resistance between the control terminals listed below and the ignition terminal 1:
   • Control terminal 1
   • Control terminal 2
   • Control terminal 3
   • Control terminal 4
   • Control terminal 5
   • Control terminal 6
   • If less than the specified value, replace the master window switch.
5. With the switch in the UP position, test for less than 2 ohms between the control terminals and the ignition terminal 1 listed below:
   • LR window switch control terminal 2
   • RR window switch control terminal 3
   • RF window switch control terminal 5
   • Driver window switch control terminal 5
   • If greater than the specified range, replace the master window switch.
6. With the switch in the DOWN position, test for less than 2 ohms between the control terminals and the ignition terminal 1 listed below:
   • LR window switch control terminal 3
   • RR window switch control terminal 1
   • RF window switch control terminal 6
   • Driver window switch control terminal 4
   • If greater than the specified range, replace the master window switch.

Rear Window Switch 

1. Ignition OFF, disconnect the harness connector at the appropriate rear window switch.
2. Test for infinite resistance between the control terminals 1 and 4 and the control terminal 5 with the switch in the INACTIVE position.
   • If less than the specified value, replace the window switch.
3. Test for less than 2 ohms between the control terminal 4 and the control terminal 5 with the switch in the UP position.
   • If greater than the specified range, replace the rear window switch.
4. Test for less than 2 ohms between the control terminal 1 and the control terminal 5 with the switch in the DOWN position.
   • If greater than the specified range, replace the rear window switch.

Window Motor 

1. Ignition OFF, disconnect the harness connector at the appropriate window motor.
2. Install a 25A fused jumper wire between one of the control terminals and 12 V. Momentarily install a jumper wire between the other control terminal and ground. Reverse the jumper wires at least two times, the window motor should perform the UP/DOWN functions.
   • If it does not perform as specified, replace the window motor.
