xenons going down when wet

Hi! I have problem with xenon headlights in my 197. When is dry they going up and staying in this position. When is wet they going up and slowly dropping down to lowest position (If I turn off engine they stopping). I also unplug rear sensor but there is no change. Any suggestions? Thank's
 
OK so maybe someone know where is fuse for headlight adjuster motor? Is there also manual adjusting (by screw or something) like in normal headlights? Thank's
