Common Symptoms
- Warning light or message on dashboard related to the power seat system
- Seat memory settings not saving or recalling correctly
- Power seat won't move in one or more directions
- Diagnostic trouble code (DTC) stored in module memory
Possible Causes
- Failed seat motor/module — internal fault from age, heat cycling, and vibration
- Damaged wiring or corroded connector in the power seat system circuit
- Blown fuse for the power seat system circuit — check before replacing components
- Faulty control module driving the seat motor/module
- Loose or corroded ground point shared by the power seat system
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($4-143 at shop, free at auto parts store for basic scan)
- Visually inspect the power seat system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $76 diagnostic fee at shop)
- Replace seat motor/module if testing confirms it has failed — use OEM quality, avoid the cheapest no-name aftermarket parts that fail in a year ($100-800)
- Check and replace any blown fuses in the power seat system fuse circuit — if fuse blows again, there's still a short that needs to be found ($2-20 for fuses)
- Perform a wiggle test on the power seat system wiring harness while monitoring live data — see if the fault returns when you move the harness at different points ($0-133 diagnostic labor)
