    If less than infinite resistance between the signal terminals E and F and the B+ circuit terminal B with the LR Switch in the INACTIVE position
     
    If greater than 2 ohms of resistance between the signal terminal E and the B+ circuit terminal B with the switch in the UP position
     
    If greater than 2 ohms of resistance between the signal terminal F and the B+ circuit terminal B with the switch in the DOWN position
     
    If less than infinite resistance between the signal terminals G and H and the B+ circuit terminal B with the RR Switch in the INACTIVE position
     

  8.  
  9. If greater than 2 ohms of resistance between the signal terminal G and the B+ circuit terminal B with the switch in the UP position

    If greater than 2 ohms of resistance between the signal terminal H and the B+ circuit terminal C with the driver window switch in the DOWN position
     
    If less than infinite resistance between the signal terminals B and A and the B+ circuit terminal B with the passenger switch in the INACTIVE position
     
    If greater than 2 ohms of resistance between the signal terminal B and the B+ circuit terminal B with the switch in the UP position
     
    If greater than 2 ohms of resistance between the signal terminal A and the B+ circuit terminal B with the switch in the DOWN position

  7. Replace the passenger window switch for the following conditions:

    If less than infinite resistance between the signal terminals G and F and the B+ circuit terminal A with the switch in the INACTIVE position
     
    If greater than 2 ohms of resistance between the signal terminal F and the B+ circuit terminal A with the switch in the UP position
     
    If greater than 2 ohms of resistance between the signal terminal G and the B+ circuit terminal A with the switch in the DOWN position
     

  8.  

Window Motor
  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Install a 30-amp fused jumper wire between the control terminal A and 12 volts.
  4.  
  5. Momentarily install a jumper wire between the control terminal B and a ground. The appropriate window motor should perform the UP or DOWN function.
  6.  
  7. Reverse the jumper wires. The appropriate window motor should perform the DOWN or UP function.
