Camry headlight motors out of sync

[wedgehog]

Hi guys, there doesn't seem to be a section for Camry, or have I got the last one :-) so I posted this here.

Looking at my headlights on a wall with the car about 15 feet away and operating the motor wheel to adjust them down, they start at the same level, then the left beam moves a third more down than the right. Is there any adjuster for setting how long the motor runs for? I have taken the headlight off and checked the swivels and the plastic coupling to the end of the motor spindle, all ok.
