Frequently Asked Questions

Why does my power seat not remember its position?

The seat position sensor provides feedback to the memory module. A failed sensor prevents accurate position storage or recall.

Can I still adjust the seat manually?

Yes, power seat switches still work but memory recall will not function until the sensor is repaired.

Is this related to seat heater problems?

No, the position sensor circuit is separate from seat heater circuits, though both share the under-seat harness.
