Help: Auto Leveling No Longer Working After Clear Lens Swap

Just did the clear projector lens swap with the rv shield delete and wow what a difference! Aimed my headlights and everything, but I have a problem... Auto leveling no longer is working. When I turn the key to position 1, I hear a noise sorta resembling a horn, then position 2 and the lights don't auto level anymore.

Does anyone know if the auto leveling will cease to function entirely if one light has a fault? Additionally what could be causing the fault? Does the dial adjuster closest to the fender affect this in any way? I'm going to try taking apart the passenger one again when I get a chance, but would greatly appreciate it if someone knows what's wrong. Thanks!

Did you hook up the motor arm to the assembly itself?

So I took both headlights apart last night and discovered the noise I was hearing ended up being the level arm and clip disconnected from the headlight bowl housing, so I reconnected that and the auto leveling began to function 100% normal. Unfortunately, the passenger side, no matter how many times I tried, there seems to be some resistance from the housing as the auto level motor does seem to be working fine, but the noise is it attempting to moving the assembly, but it can't since it seems something is stuck. At this point, I'm thinking something got bent, but I'm not entirely sure.

If anyone has any ideas I'd greatly appreciate it. Would prefer not to have to buy a new headlight. Thanks

FIXED!


After cycling the lights with the bezel assembly loosely connected allowing the auto level arm to move unobstructed. Made the same gear noise with no movement, so it seemed clear at this point that the gear arm was seized. Ordered a new auto level arm assembly, got it in today, hooked it up and bam everything works perfect! Thanks guys!
