2. Test for infinite resistance between the B+ terminal D and each control terminal listed below with the switch in the open position.
   • terminal B
   • terminal E
   • If less than infinite resistance 

     Replace the S64 Seat Adjuster Switch.

   • If infinite resistance 
3. Test for less than 2Ω between the B+ terminal A and each control terminal listed below with the appropriate switch in the closed position.
   • terminal B
   • terminal E
   • If 2Ω or greater 

     Replace the S64 Seat Adjuster Switch.

   • If less than 2Ω 
4. Test for less than 2Ω between the ground terminal A and control terminal B with the switch in the open position.
   • If 2Ω or greater 

     Replace the S64 Seat Adjuster Switch.

5. Test for less than 2Ω between the ground terminal C and control terminal E with the switch in the open position.
   • If 2Ω or greater 

     Replace the S64 Seat Adjuster Switch.

   • If less than 2Ω 
6. All OK.

Seat Motor

1. Ignition OFF, disconnect the harness connector at the M55 Seat Rear Vertical Motor.
NOTE:

When performing the following tests, make sure that the seat is not already in the position the test is attempting to produce.

2. Install a 30A fused jumper wire between control terminal 1 and 12V.
3. Momentarily install a jumper wire between control terminal 5 and ground. The seat motor should momentarily perform the appropriate UP/ DOWN function.
   • If the motor does not perform the UP/ DOWN function 

     Replace the M55 Seat Rear Vertical Motor.

   • If the motor performs the UP/ DOWN function 
4. Reverse the jumper wires; the motor should perform UP/ DOWN function.
   • If the motor does not perform the UP/ DOWN function 

     Replace the M55 Seat Rear Vertical Motor.

   • If the motor performs the UP/ DOWN function 
5. All OK.
