i am having trouble with my headlights, they go up and down fine and they were just recently rebuilt w/ the new brass gears,

but they do the click thing and they get REALLY hot and they drain my battery which is a pain cause i have to jump it all the time,

i would go try to figure it out on my own but i don't know anything about the headlights except for the motors themselves

i did do a 30 min search and couldn't come up w/ anything helpful, and i don't wanna waste the money i just spent on a rebuild by switching to the 2nd gen (altho i would like to sometime)

thanks for the help, Travis

The limit switches may not be operating correctly, they should shut down power to the motor at travel limits.

yep, the switches are not cutting the motor off. You must disassemble the motor again and reassemble it a notch closer or further, depending on which way it's not shutting it off. You can take the cover of the motor off and while still installed, see which way it's not turning off the switch. You can even make contact to make sure. Good luck.

Mine are doing the same thing on my 85 coupe. I called Rodny because I allso rebuilt them with his gears. He said that there wasn't enough electrical power to torgue the swithes off. But I don't know just how to fix it. It is JUST a paine in the butt. The car is just my back up ride incase one of my other cars is down,and I try not to drive it at night.But good luck anyway.

ok, what notch are you talking about? i've been inside the motors and the only notches i saw were on the gears, thanks for the responses

There are several things that can cause this:

First make sure that the rubber grommet on the end of the shaft got postioned correctly when you reassembled the motors. If it's sitting outside the case it will interfere with proper operation of the limt switches. The following link has pictures of this and other good info on a rebuild.

Second the motor rotor needs to be able to slide up and forth to be able to open the switches. If you didn't oil or grease the bushing on the rotor before reassembly this could also be problem.

Third it can be dirty contacts on the relays. If there is a voltage drop across the relay then the motor doesn't operate at full power and won't have enough torque at the end of travel to shift the rotor to open the limit switch. The solution is to clean the contacts or replace the relays.

If the limit switch doesn't open at the end of travel the motor will cycle on and off on the thermal overlead switch. After a motor is reinstalled watch it closely for a couple of minutes. If you see it intermittently click on and off, the limit switch hasn't opened and it cycling on the thermal overload.
