Lately my power driver's seat does not move. None of the 8-way positions work at all. But I hear the relays under the seat clicking away.

But then if I drive the car for a few miles it starts working again.

Any ideas?

I'm thinking it might be a bad connection between the relays and the seat motor? Or the relays themselves are bad? Any way to test them? Are they located in that black plastic box under the seat with the wires running to it? How do you remove them?

Any help appreciated, thanks.
