Changed right headlight on 2006 toyota avalon with self leveling headlights and now the self leveler on the drivers side does not work

SOURCE: Recently purchased a Certified Pre-Owned 2006 LE.

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.

I WOULD SUGGEST GETTING A NEW THERMOSTAT, USUALLY DONT COST MUCH AND WILL FIX THE PROBLEM RIGHT AWAY

There is an issue with the height control sensor on the Prius product. Is it still under warranty? If not, go back to the dealer and tell them that you want scheduled to see the District Service and Parts Operations Manager. When you meet with him/her, explain the situation, and the costs involved. He/she has the ability to grant "goodwill" assistance, and possibly help you out on the repair, with Toyota participating in some of the costs.
Can't hurt to try. More often than not, the DSPOMs are very flexible, and like to promote customer satisfaction.
