Frequently Asked Questions

Why does my seat keep going to the lowest position?

A low circuit makes the BCM think the seat is at its lowest, so memory recall cannot adjust height properly.

Can a pinched wire cause this?

Yes, wires in the seat track mechanism can get pinched during movement, causing short circuits.

Is this expensive to repair?

Typically $70-$320 depending on whether it is a wiring repair or sensor replacement.
