I was wondering how to fix the timing on my headlights on 1997 Pontiac Firebird

When i turn my lights on, the lights keep going up and down constantly and after 15 seconds or so, then one will stay down and other one will be up or then will be half way, you never know, so when i want to put them down or up i have to unhook it and do it manually then i turn the lights on, so i was wondering how to time it

They are not adjustable, check you fuses and relays, possible bad switch and or headlight motor..
SOUNDS LIKE A WEAK OR BAD HEADLIGHT RELAY,START THERE
