Buick Repair Questions? Ask a Mechanic for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question.

To help you determine which, I need to know the year and model of your Buick, as well as whether you hear any noise from the motor when you try to adjust the seat. And whether it moves up and down or if those are lost as well
