I am reinstalling the headlights, brackets, pivots, etc after having the car repainted. All works well on the RH side. Headlight lights up and it opens and closes. On the LH side the headlight lights up in the closed position. It will not open and close. I have replaced the relay with one I know is good. The ground wire is tight. No blown fuses in the fuse panel. The nut that holds the lever to the splined post on the motor seems tight enough. If I manually turn the black knob at the back of the motor, the light will cycle open and then close.
Electrical problem somewhere? What do the 3 wires do that plug into the 3 wire plug coming from the motor? Red = power? Does this wire give power to the motor AND the headlight? Green??? Gray??? I thought headlight motors were pretty much bulletproof, last forever. Maybe not. If anyone has a suggestion on how to attack this problem and what I should look at first, please let me know. . Thanks in advance for the advice. |

If not bad motor or connections to motor. (IMG:style_emoticons/default/biggrin.gif) |

(IMG:style_emoticons/default/biggrin.gif) Old thread from search...I am experiencing this on the driver side; passenger side works fine. The motor does take over when I turn the knob. Is it really a switch issue? |
