My passenger side motor works sometimes, others, not so much. I recently put a new gear in too. It's not free wheeling, it's jusd dead. I grabbed a speaker wire ad ran power to the motor from the drivers side, and it worked fine. That this tells me, is there's a bad circuit. What's the best way to pinpoint the issue? I did put some electric grease on the contact, that might haven worked, I'm not sure. Like I said, it's intermittent.
------------------ I have a 1987 Fiero, 4 cylinder 5 speed. With an 88 engine.
If its a pre 87 it may be the isolation relay. In my 86 I cant just turn the switch on, I have to partially push it till the lights come up, then switch it the rest of the way on. This is because the out of production iso. relay is bad.
If the connector(s) are bad loose etc. then the module will think the motor(s) are stuck and shutdown. May mean module is going bad.

I tried to raise the headlight with the knob, it would hardly budge at first, then it loosened right up. I decided to hit the switch, just to see, and it opened up just fine, turned the lights off, and it retracted properly. Tried again, up and down, and it worked perfectly.
I don't think it's fixed yet though, what do you guys think?
when you replaced the gear, did you use a nylon one or aluminium? If you hadn't just replaced the gear, I'd say you have all the symptoms of a stripped gear, and manually turning the knob moved the motor into a position where it could grab a good tooth.
Most likely a low voltage problem. Many causes. Mostly poor engine/frame grounds. Rust under the copper ends on the frame grounding wires in various locations. Connectors getting slightly corroded etc. Relay contacts in the controller. Many places or most likely just a bit in multiple places all adds up.

@net. I used a plastic gear. I used epoxy as a substitute for the little bushings that were out. Got the idea for the epoxy from one of buddycraigs videos.
I called you the other day about the slave cylinder. It was the one the 87 with the 88 motor. The new style RD master cylinder did work, the clutch works perfectly now, thanks. I appreciated your conversation, you saved me a lot of trouble. That bench bleeder thing was a nice touch too, kudos on that.
In addition to my post above: It take a lot more electrical energy to start a motor turning than to keep it turning. Once turning it takes less energy. That is why it will not start sometimes. Just turning the knob some releases some of the pressure and the motor can now start turning once the switch is turned on.

Hi I'm having the same sort of trouble. Passenger headlight will come up if it turn it manually and then go up and down correctly on it's own as many times as I try it. Once I let it sit for longer than a minute it needs help again. It doesn't matter of the hood is opened or closed. Do you think its the module or a ground issue?
