I have a 91 GS. When I bought it the guy told me that the driver side flip up motor was not working, which wasn’t a big deal to me. Shortly after I bought the car I plugged the motors in to check them. Indeed, the passenger side worked but the driver side didn't. I got a replacement motor recently from a parts car. Before I installed it I plugged it in to make sure it worked and it did spin when I hit the flip ups button. Now, after installing it, neither of the motors work. My friend and I check the relay and the fuse and both are good, so we are both lost as to why they are not working. If anyone has any idea as to what I should try, please let me know. Any ideas or suggestions are greatly appreciated!! Thanks!

Gonna be a PITA but take them out and make sure you didn't break anything putting them in. Or over tightened the swing arm by accident.

just watch out with those motor they can brake your fingers. :grin:
I think you need to trase the wire and find out where is the problem
