I just replaced both of my headlight motors with rebuilt ones a few months ago, and have worked great, but over the course of time the passenger side motor has lifted quite a bit slower than the driver side one. It seems to almost struggle, still going while the other raises quickly and easily. Could this be a ground wiring issue?

I'd honestly be happy with both headlights going up and down for an 86 (im assuming.)

From what I've seen, even brand new fiero's had one headlight always be quicker than the other. But for your case, that does seem strange. It could be 10,000 different things, but I'd assume it's the isolation relay.

Here is more info about the 1st gen system:

my cave link above might help.

Iffy power and/or ground for that motor and relays can cause problems.
Just one weak connection anywhere is enough. Can be connection inside the motor or iffy relay.
why? See my Cave, Electric Motors

Probably just my OCD flaring up. I'll check the ground connections and relay. I just get the feeling that the passenger side one is on its way out already, given the lack of stability of these 1st-gen motors. If these go out, I'll try to put the effort into converting to the 2nd gen motors.
