Bizarre Headlight Behavior
Hi all. Searched through the posts and although there is an immense amount of information on the blinking headlight, there isn't anything I could find that helps with the bizarre behavior of my headlight. I was on a trip and had the hood up to check fluids. Normal enough. Dropped the hood and as soon as the hood hit and latched shut, the headlight gear on the passenger side went nuts. When I say went nuts, I mean nuts - it spins continously at high speed until I unplug it. I can then manually rotate the light and still turn it on and off but would like to make the tasmanian devil spinning stop. I am trying to figure out if it is the internal gears or the relay. I have talked to a couple friends of mine who are also C4 owners and gotten different opinions. My C4 is a 1987. Any help I can get is great. Also, anyone even know where the headlight relay is located? Is it on the fenderwall in between the driver light and tire? If so, easy enough to replace.
Thanks everyone.
Thanks everyone.

No personal experience, but I can tell you there are 3 relays that control the headlight doors. You might find some help here http://members.shaw.ca/dankai/Headlight%20Doors.pdf.

Thanks for the help!!!
Hi Agent 86 and RandyJ75. Those links were both helpful. The PDF of the headlight wiring showed me where the different relays are so if that ends up being the problem, I know where to look. I ended up ordering a set of gears for the motor from MAM which I think I will rebuild anyway based on all the posts about them going bad. Thanks for all your help!
