Preliminary Checks

Check POWER ACC fuse (25-amp), located in instrument panel fuse block.
Ensure terminal contact and ground connections are clean and tight. Check for proper installation of aftermarket electronic equipment.
Check for any obstruction under seat or carriages which may affect power seat operation.
If seat motor internal circuit breaker is tripped, it will reset when voltage is removed from motor.
Check for broken or partially broken wire inside of insulation, which could cause system malfunction but prove good in a continuity/voltage check with system disconnected. These circuits may be intermittent or resistive when loaded.
If motors operate but seat does not move, check for obstruction in seat drive rail or check for broken drive gear. If seat tilts forward and/or rearward but does not move up or down, replace power seat switch.
