Headlights turn on but won't raise or lower
I’ve recently run into a problem where both of my headlights won’t automatically raise or lower yet the lights work. I’ve tried searching but the results don’t quite match my symptoms. Some have only one that refuses to cooperate, or doors function but lights don’t turn on, or the thread doesn’t provide a conclusion with their findings. I’m trying to determine if I should be looking towards the headlight control module or BCM or something other. Info is below.

- Sun Guns (installed 6+ years ago)
- 4 HI wire harness (installed 8+ years ago)
- Twilight sentinel installed / activated (8+ years ago)
- Headlights won’t go up or down
- Chime activates when door is open as if headlights are on
- Headlights work via MFS or Twilight Sentinel
- Doors open smoothly when manually opened and no weird noises prior to problem
- Turning on the high beams does not help
- Pulled fuses 3 & 4 (engine compartment – L & R headlamp motors) which stopped the chime
- Purchased new relay and swapped with #43 & #44 with no change

I recently had one headlight that did not raise. I jiggled the wiring harness to the headlight and wallah, it went up. Cleaned all the connectors and no further problem. Realizing having two headlights with the same wiring problem would be very usual, but Murphy's law sometimes happens.

I have a left (drivers side) headlight pump that's is bad, so I am going to replace both. I would like to install No Fault LED lights as well at the same time. Do I need a new headlight housing unit or can I just purchase pulps and replace. Factory lights are just adequate! Mine is a 2002 C5 coupe.
