Hey NAM, I had to remove my passenger side headlight the other day and upon reassembly the whole light doesn't work. The low, high and blinkers all refuse to turn on. I also realized that the horn in the car does not work either, and I believe that it is connected to the headlight not working. I did not take the headlight apart, I just removed the 4 bolts, unplugged it and pulled it out. I have checked fuses and they all seem ok, what could it be? When I press the horn I do hear a clicking from the fuse box but the fuse looks fine... Any ideas on what this could be?

 

only the right side isnt working? did you try to disconnect the batter and reconnect it again?

 

The Bentley wiring diagram doesn't show any correlation between the horn and the headlights. Could this be coincidental? Did the horn work before you removed the headlight? FWIW, there should be a fuse and a horn relay in the fuse box in the pax foot well. Are you sure the headlight connector is properly connected?

 

I figured it out, when I removed the light and plugged it in while the light was detached ti decided to work.. Not sure why this was an issue.
