Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / December 20041990 Pontiac Grand Prix No Hi-beam problem
The hi-beams on my son's car have quit working and I am puzzled. With the ignition switch on and the headlights on, the hi-beams will not come on. However, with the ignition off and headlights off, you can pull on the switch and the hi-beams will come on. You used to hear a click when you pulled the hi-low beam switch and you no longer hear the click. At first I thought that there was a latching type relay between the switch and the bulbs, but the only wiring diagram I have, in a Haynes manual, shows that the headlights are powered directly from the hi-low beam switch. I don't understand. If the hi-beam switch itself is bad, why will the hi-beams come on when you pull the switch with the ignition is off? What am I missing? You might be missing a ground connection. > The hi-beams on my son's car have quit working and I am puzzled. > [quoted text clipped - 12 lines] > > What am I missing?

If the ground at the bulb is bad, the hi-beam wouldn't light at all. >> The hi-beams on my son's car have quit working and I am puzzled. >> [quoted text clipped - 12 lines] >> >> What am I missing? Those are 'passing' lights I believe and consist of both the high and low beams together when you pull the stalk back. Maybe they are both burned out?

I don't know if the low beams are supposed to stay on when you pull the stalk. What puzzles me is why the high beams don't work when you have the headlights turned on and pull the stalk but will come on when the headlights are off and you pull the stalk. >> The hi-beams on my son's car have quit working and I am puzzled. >> [quoted text clipped - 12 lines] >> >> What am I missing? |
