Headlight motor question.....
Here's my problem, my headlights go up by themselves, but will not go down by themselves. I can manually wind them back down and then apply power to the headlights and they will come back up just like they are supposed to. I can also apply power directly to the motor and get them (each) to go up and down by themselves. The car is an '85, but it has been updated to a module controlled system by a previous owner. I swapped out the module with a new one with no luck. I haven't had a chance to put a meter on it yet because the only schematic I have is for the relay controlled system. Can anyone shed some light (sorry I couldn't resist :D ) on my problem?? What kind of signal is the module supposed to get to tell it to go down? Or is it just a matter of "lack of" voltage? Any help would be great. Thanks,

Re: Headlight motor question..... (anchami)
You say it has been ubgraded to the 88+ style? It sounds like a bad actuator to me... Was the new actuator that you got brand new or new to you?
How it works is that actuator applies power to the motors and lets them spin until they reach the extent of their travel at which time it knows to stop, then to retract the lights, it reverses polarity and lets the motors spin in the opposite direction until they reach their full travel.
I was using a actuator for a while that would let one light extend properly and would let the other light retract properly but not vice-versa :crazy:
Have you always had this problem or is it new? If you've always had it, it could be that whoever did the upgrade did not connect all of the necesary wires (or at least not properly)...

Re: Headlight motor question..... (A)
I've owned the car for about a year and a half and it just started doing it last month. I would agree with you on the actuator, but BOTH :rolleyes: headlights started doing it at the same time. I would think that if it was an actuator, that only the affected actuator would be bad, and what's the chance of both of them going out at the exact same time?? :confused:
