Seats - Power: Testing

Power Seat Switch

1) Ensure battery is fully charged. Operate seat switch and

check for motor operation. If motors are heard operating, check

binding or for stripped drive in motor(s). If motors do not operate,

check fuse and replace if defective.

2) If fuse is okay, remove power seat switch and disconnect

connector. Using a test light, check for voltage between terminals

No. F and C. See Fig 1. If voltage is present, replace switch.

3) If voltage is not present, connect test light to a good

ground and terminals No. F. If voltage is present, repair ground wire

at terminals No. C and recheck. If voltage is not present and fuse is

good, repair short in feed wire terminals No. F.

Rear Tilt Motor

1) Install seat switch and connect connector. Disconnect

rear tilt motor connector. Connect a test light to Dark Green wire on

rear tilt connector and a good ground. Position seat switch in up

position and check for voltage. Connect test light to Dark Blue wire

and good ground. Position seat switch in down position and check for

voltage.

2) If voltage is present at both terminals, replace rear

tilt motor. If voltage is present at one terminal and not present at

other terminal, replace switch.

3) If voltage is not present at either terminal, check for

open or short in both wires from motor connector to switch. Repair as

necessary. If no short or open is present, replace switch.

Front Tilt Motor

1) Disconnect front tilt motor connector. Connect a test

light to a good ground and Light Blue wire. Position seat switch in

down position and check for voltage. Connect test light to a good

ground and Yellow wire. Position seat switch in up position and check

for voltage.

2) If voltage is present at both wires, replace front tilt

motor. If voltage is present at one terminal and not present at other

terminal, replace seat switch.

3) If voltage is not present at either terminal, check for

open or short in both wires from connector to seat switch. Repair as

necessary. If no short or open is present, replace switch.

Forward/Rearward Motor

1) Disconnect connector from forward/rearward motor. Connect

a test light to a good ground and Tan wire. Position seat switch in

back position and check for voltage. Connect test light to good

ground and Light Green wire. Position seat switch in forward position

and check for voltage.

2) If voltage is present at both wires, replace

forward/rearward motor. If voltage is present at one terminal and not

present at other terminal, replace seat switch.

3) If voltage is not present at either terminal, check for

open or short in both wires from connector to seat switch. Repair as

necessary. If no short or open is present, replace switch.
