1992 RS, Known good headlights I have tested, replaced headlight switch, checked all fuses, is there a headlight relay for this year?. All turn signals and parking lights work as well as hazards and brake lights. I purchased a new dimmer switch the one that has the rod running down the column to it. Anyone have any ideas thanks in advance for the help

 

Yes there is a relay. Check/swap out relay on box on drvr side fenderwell.
