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.
