I started my car tonight and noticed despite the headlight switch being fully in the off position, my dash lights are on and my license plate light is .
Odd. Never saw that before. Headlight switch I imagine.... Thoughts? David Addedum-and saw what I thought was a wisp of smoke come from under my dash at the windshield....perhaps my imagination? |

Today I thought I would pull the headlight dimmer switch and do a swap with another one I had and lo and behold I see my spare is quite different than what I have on my car. The one on my car has a "jumber" so I'm thinking the PO used a different dimmer and that this "jumper" is part of doing that. Notice in the image my spare has no jumper and the different number of tang contact points between the two.
Anyone have any experience with this? I suspect my spare is the appropriate dimmer. After this I can only think of one more component I can change before doing continuity checks on the wires and that would be my ignition switch (I do have a spare). Grrrrr. How bout the difference of those dimmer switchs ya'll? |

Just wire it the same way, with the jumper removed. |

My spare has the white wire at 56 and the yellow wire at 56a, but the one on the car (that's jumped) has the yellow wire at 56 and the white wire at 56a. Any thoughts about this? Here's a better image and the schematic (Believe it's component 27 combination relay, right?): |

I just pulled my fuse panel to take a look.
56 is where your Red is connected on both, as is mine. 56a is to the left and it should be White. 56b is to the right and should be yellow. Yellow with red stripe goes to S and if using a 5 post relay, a jumper should go from 56 to 30. |
