I have a 2001 volvo s80 t6 and the seat will move forward, up, down, and tilts and everything but it wont go back. I checked the switches with an ohmeter and they were all good. I was wondering if anyone had any further information. Is there one motor for forward and reverse or are they two seperate motors and also is there a drive box for the motors that could be bad? Thanks a lot for you help!

 

Same motor for foward and reverse.
Maybe it is still a problem with the switch.
