Driver seat not working intermittently--2001 V70

Post by superjodz »

Okay I've been having this problem with our 2001 V70 for quite a while now but haven't had a chance to dig into it. I posted something here about a year ago and didn't get any answers so i thought I'd try again.

The power driver seat stops working intermittently, but it's the same every time, not inconsistent.

When I come to the car in the morning and open the door, the seat controls will work. Start the car up, the seat still works. Let it run for a few minutes, and at some point the seat stops working, and won't work for the rest of the trip. All controls, not just one.

Stop the car, let it sit for a while, get back in, sometimes the seat will be working again, sometimes it won't depending on the amount of time that has passed.

I did manage to come across some information that was interesting. I read that upon initial startup there is one computer (or module) that is in change of managing the seat controls, but after a few minutes it transfers to a different one?? If that's the case it would make sense that the second unit is working properly.

I'm pretty sure it's not wiring or seat motors, it has to be computer related. Any ideas????
