Component Testing

Window Motor

1. Ignition OFF, disconnect the harness connector at the appropriate Window Motor.
2. Install a 20 A 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 and DOWN functions.
   • If the Window Motor does not perform the UP and DOWN functions 

     Replace the Window Motor.

   • If the Window Motor performs the UP and DOWN functions 
3. All OK

Driver Window Switch

1. Ignition OFF, disconnect the harness connector at the Window Switch-Driver.
2. Test for infinite resistance between the terminals listed below with the switch in the open position:
   • Ignition terminal C and control terminal A
   • Ignition terminal C and control terminal D
   • Ignition terminal C and control terminal G
   • Ignition terminal C and control terminal H
   • If less than infinite resistance 

     Replace the Window Switch-Driver.

   • If infinite resistance 
3. Test for less than 3 Ω between the terminals listed below with the switch in the open position:
   • Ground terminal F and control terminal A
   • Ground terminal F and control terminal D
   • Ground terminal F and control terminal G
   • Ground terminal F and control terminal H
   • If 3 Ω or greater 

     Replace the Window Switch-Driver.

   • If less than 3 Ω 
4. Test for less than 3 Ω between the terminals listed below with the switch in the Up position.
   • Driver window - ignition terminal C and control terminal G
   • Passenger window - ignition terminal C and control terminal A
   • If 3 Ω or greater 

     Replace the Window Switch-Driver.

   • If less than 3 Ω 
5. Test for less than 3 Ω between the terminals listed below with the switch in the Down position:
   • Driver window - ignition terminal C and control terminal H
   • Passenger window - ignition terminal C and control terminal D
   • If 3 Ω or greater 

     Replace the Window Switch-Driver.

   • If less than 3 Ω 
6. All OK

Passenger Window Switch

1. Ignition OFF, disconnect the harness connector at the Window Switch-Passenger.
2. Test for infinite resistance between the terminals listed below with the switch in the open position:
   • Ignition terminal A and control terminal G
   • Ignition terminal A and control terminal F
   • If less than infinite resistance 

     Replace the Window Switch-Passenger.

   • If infinite resistance 
3. Test for less than 3 Ω between the control terminals listed below with the switch in the open position:
   • Control terminal H and control terminal G
   • Control terminal D and control terminal F
   • If 3 Ω or greater 

     Replace the Window Switch-Passenger.

   • If less than 3 Ω 
4. Test for less than 3 Ω between the ignition terminal A and the control terminal G with the switch in the Up position.
   • If 3 Ω or greater 

     Replace the Window Switch-Passenger.

   • If less than 3 Ω 
5. Test for less than 3 Ω between the ignition terminal A and the control terminal F with the switch in the Down position.
   • If 3 Ω or greater 

     Replace the Window Switch-Passenger.

   • If less than 3 Ω 
6. All OK
