I've been searching and reading trying to find a way to effectively test my headlights without going into traffic and jamming on the brakes. I also can't find I clear answer on if the lights on my 06 mcs are supposed to auto adjust full time (left right up and down) while driving or just up and down? I notice them do the test when I first turn them on, but after that I feel like they just stay there.

 

What about using a floor jack and a wall to watch the beam pattern? You can also manually move the arm on the leveling sensors to see if the headlights move.

 

I did this, and I didn't really notice any movement at all. Maybe a flicker if that

 

yes, unbolt them and see if they move with the lights. 37146784698 & 37146853759

One on the front and one on the rear.

I set the e-brake and put car in reverse, let out clutch a little it will lift the rear of car a little. Then same in first gear, it will squat the rear of the car. A masking tape line/reference point on garage door. Mine say at same point on tape line.

 

I have moved each sensor individually with no movement. When I'm out playing in town you can watch the headlights bounce with the car, even with the ebrake trick, headlights move with the car

 

Did you check the connections at the plugs and the fuse for the headlight sensors.

 

The front plug is broken but is still making connection.
Having a tough time finding the fuse for the sensors themselves

 

Weird...I'd think if they move during initially turning them on, they work. I didn't think they move instantaneously with movement of the sensors either...But it's been awhile since I tested. I'll look in the morning and when I get off work and pinpoint the fuse(s).
