Answer

its either your headlight its self or your plug in to the head light.


If I remember correctly, the '79 still had the dimmer switch mounted on the floor. Check the connection to the switch. You may need a new switch....they run about $10. If it is the turn signal mounted switch, it will be a little more difficult to change.

Where is the switch location for changing from high beams to low beams on a 1989 Pontiac Grand Prix?

It should either be on the dash board where you can turn your interior lights on or you should pull back on the directional to switch. Cars run with the low beams on and the high beams are switched to in the dark when you feel you need extra light. I feel bad for the people that have been coming in the other direction from this car if its high beams have been on constantly.
