The limit adjusting screws on the side of my Chamberlain Garage door do not seem to have any effect when I turn them. Am I doing something wrong in trying to adjust as my door won't stay down?

1. For first time training, press and hold the two outer HomeLink buttons, releasing only when the HomeLink indicator light begins to flash after 20 seconds. (Do not perform this step when training the additional HomeLink buttons.) 2. Position the hand-held transmitter 1-3 inches away from the HomeLink surface (located on your visor), keeping the HomeLink indicator light in view.
3. Using both hands, simultaneously press and hold both the desired HomeLink button and hand held transmitter button. DO NOT release until the HomeLink indicator light flashes slowly and then rapidly. When the indicator light flashes rapidly, both buttons may be released. (The rapid flashing indicates successful training.)
Note: Some garage door openers may require you to replace step 3 with the “cycling” procedure noted in the “View Canadian Instructions” section.
4. Press and hold the trained HomeLink button and observe the indicator light.

• If the indicator light is solid/continuous, training is complete and your device should activate when the HomeLink button is pressed and released.
• If the indicator light blinks rapidly for 2 seconds and then turns a solid/continuous light, proceed with the following training instructions for a rolling code device. A second person may make the following steps quicker and easier. Please use a ladder or other device. Do not stand on your vehicle to perform the next steps.

I had to rebuild the headlight motor gears on my 89 last year. There is a plastic gear in the headlight assembly that has little plastic "barrels" in it for tension. These little bushings disentigrate over a short period of time. both of mine went out about a month apart. They are called the Delrin Bushings and sell for 8.99 a set (MAdirect). sometimes the plastic gear get's damaged, so you may want a kit. I used a new plastic set don't recall how much, they also sell brass for $59 each side. I figure the plastic lasted 20 years last time. It is not for the novice, but it wasn't too hard if you have the right tools. second side took me an hour. good instructions.

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.
