Component Testing

Driver Window Switch

1. Ignition OFF, disconnect the harness connector at the driver window switch.
2. Test for less than 2 ohms between the lockout control terminal F and the B+ terminal E with the lockout switch in the ENABLE position.
   • If greater than the specified value, replace the driver window switch.
3. Test for infinite resistance between the lockout control terminal F and the B+ terminal E with the lockout switch in the DISABLE position.
   • If less than the specified value, replace the driver window switch.
4. With the switch in the INACTIVE position, test for infinite resistance between the appropriate control terminals and the B+ terminal E listed below:
   • LR window switch control terminals D and C
   • RR window switch control terminals G and H
   • RF window switch control terminals B and C
   • Driver window switch control terminals A and E
   • If less than the specified value, replace the driver window switch.
5. With the switch in the UP position, test for less than 2 ohms between the appropriate control terminals and the B+ terminal E listed below:
   • LR window switch control terminal D
   • RR window switch control terminal G
   • RF window switch control terminal B
   • Driver window switch control terminal E
   • If greater than the specified range, replace the driver window switch.
6. With the switch in the DOWN position, test for less than 2 ohms between the appropriate control terminals and the B+ terminal E listed below:
   • LR window switch control terminal C
   • RR window switch control terminal H
   • RF window switch control terminal C
   • Driver window switch control terminal A
   • If greater than the specified range, replace the driver window switch.

Front Passenger Window Switch

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

Rear Passenger Window Switch

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

Window Motor

1. Ignition OFF, disconnect the harness connector at the appropriate window motor.
2. Install a 25-amp fused jumper wire between the control terminal A and 12 volts. Momentarily install a jumper wire between the control terminal B and ground. The window motor should perform the UP/DOWN function.
   • If the function does not perform as specified, replace the window motor.
3. Reverse the jumper wires. The window motor should perform the DOWN/UP function.
   • If the function does not perform as specified, replace the window motor.
