1. 1) MEASURE DRIVER POWER SEAT SWITCH FUSED B(+) CIRCUIT VOLTAGE NOTE: Inspect Fuse 22 located in the Underhood Accessory Fuse Block. If the fuse is open, repair the cause of the open fuse before continuing. Turn the ignition off. Disconnect the Driver Power Seat Switch harness connector. NOTE: Check connectors - Clean/repair as necessary. Turn the ignition on. Measure the voltage of the Fused B(+) circuit at the Driver Power Seat Switch harness connector. Is the voltage above 10 volts? Yes Go to step 2) . No Repair the Fused B(+) circuit for an open. Perform «BODY VERIFICATION TEST»(ref-250677-S13769317432007031500000) .
2. 2) MEASURE DRIVER POWER SEAT SWITCH GROUND CIRCUIT RESISTANCE Turn the ignition off. Measure the resistance between ground and the Driver Power Seat Switch Ground circuit. Is the resistance below 5.0 ohms? Yes Replace the Driver Power Seat Switch. «(Refer to ELECTRICAL/POWER SEATS/DRIVER SEAT SWITCH - REMOVAL)»(ref-250678-S31700272722007031500000) . Perform «BODY VERIFICATION TEST»(ref-250677-S13769317432007031500000) . No Repair the Ground circuit for an open. Perform «BODY VERIFICATION TEST»(ref-250677-S13769317432007031500000) .

1. 1) MEASURE PASSENGER POWER SEAT SWITCH FUSED B(+) CIRCUIT VOLTAGE NOTE: Inspect Fuse 21 located in the Underhood Accessory Fuse Block. If the fuse is open, repair the cause of the open fuse before continuing. Turn the ignition off. Disconnect the Passenger Power Seat Switch harness connector. NOTE: Check connectors - Clean/repair as necessary. Turn the ignition on. Measure the voltage of the Fused B(+) circuit at the Passenger Power Seat Switch harness connector. Is the voltage above 10 volts? Yes Go to step 2) . No Repair the Fused B(+) circuit for an open. Perform «BODY VERIFICATION TEST»(ref-250677-S13769317432007031500000) .

1. 1) TEST THE POWER SEAT RELAY CIRCUIT NOTE: Inspect Fuses 21 and 22 located in the Underhood Accessory Fuse Block. If the fuses are open, repair the cause of the open fuse before continuing. Turn the ignition off. Disconnect the Power Seat Relay. NOTE: Check connectors - Clean/repair as necessary. Connect a jumper wire between cavity 8 and cavity 2 of the Power Seat Relay harness connector. Actuate the Driver and Passenger Power Seat Switches. Did the Driver and Passenger Power Seats move? Yes Replace the Power Seat Relay. Perform «BODY VERIFICATION TEST»(ref-250677-S13769317432007031500000) . No Go to step 2) .
2. 2) MEASURE POWER SEAT RELAY FUSED B(+) CIRCUIT VOLTAGE Disconnect the jumper wire. Measure the voltage of the Fused B(+) circuit at the Power Seat Relay harness connector. Is the voltage above 10 volts? Yes Go to step 3) . No Repair the Fused B(+) circuit for an open. Perform «BODY VERIFICATION TEST»(ref-250677-S13769317432007031500000) .
3. 3) MEASURE POWER SEAT RELAY GROUND CIRCUIT RESISTANCE Measure the resistance between ground and the Ground circuit. Is the resistance below 5.0 ohms? Yes Repair the open circuit between the Power Seat Relay harness connector and the Underhood Accessory Fuse Block. Perform «BODY VERIFICATION TEST»(ref-250677-S13769317432007031500000) . No Repair the open Ground circuit between the Power Seat Relay harness connector and ground. Perform «BODY VERIFICATION TEST»(ref-250677-S13769317432007031500000) .
