So I just finished with up putting my refurbished steering column in my car. The headlights for some reason won't come on now, but worked before the column was pulled. They doors will come up, but the lights themselves don't turn on (including high beams). All other lights work including fog lights. I did a search and didn't find anything. And all the fuses were ok.

I don't think it is the control module as I believe that controls the up/down movement of the doors, and it isn't the headlights themselves, as I just replaced them 3 weeks ago. The connections to the headlights themselves are tight and not corroded.

The only thing I can think it would be would be that there is a bad ground somewhere.

 

After checking out several possible problems, it turned out that I just forgot to reconnect the dimmer switch when I had the column out last weekend.
