Driver Headlight Bumper Stop Issue

[jrizz1]

Problem: The "Down" bumper stop on the drivers side of my 2000 will break off every 2-4 weeks causing the headlight unit not to stay in the down position, and to pop up about half way. I believe the arm is hitting the stop with to much force and breaking it. I have been replacing the bumper stop and the issue keeps returning. I have probably gone thru about 6 of the white plastic stops.

History: The problem started when I needed to replace the stripped plastic gear of the headlight motor. I replaced it with the brass gear.

Question: Is there a preset position to be in when I replace the stop. If you manually turn the knob on the motor clockwise without a stop in place, the headlight unit will continue to cycle up and down.

Thanks for any advise.

The motor is supposed to stop by increased current draw being monitored by the headlight control module. No limit switches. I am surprised to hear when the "down" bumper breaks the headlight goes to the half way up position.

I have never worked on the headlight assemblies, just done diagnostics on the electrical system for people. The FSM was no help, I looked.

I also found this link for a guy who makes the brass gear and makes a "tougher" bumper stop that may be your solution. Suggest you contact him.
