Flip-ups not working

I have a 91 Eclipse GS. When I bought it the guy told me that the driver side flip up motor was not working, which wasnt 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 reciently from a parts car. Before I installed it I pluged 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 freind 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!

id start looking at the wiring. Usually headlights are run in series so you may have messed up the wiring with the new headlight causing neither to work. Other than that i can only think of the fuse or relay. Make sure you are looking for the ones for the motor and not the headlight lamp

i had the same problem fixed the then the other went out and i have the perment fix i upgraded my 91 front end to a 93 front in everything bolted up only had to drill a few hole for the headlights

Check your headlight switch.
