hey guys need a little help but this problem isn't for my car... its for my dad's Buick... the problem is that when the lights are on at night... the left blinker and hazards don't blink... it turns on but does not flash... the right blinker works fine... and when the lights are not on... both blinkers work okay... does neone have any idea what could be wrong??? a bad relay??? all the fuses and bulbs are okay... i checked a few relays i thought could be the problem but i think the electronics is a little screwed up... please help if neone can.. thanks alot in advance...
