There are two headlight fuses in the engine compartment fusebox. one for each side. keep an eye on them. also, go ahead and change your bulbs (wether sealed beam or Halongen swap bulbs).

I have a 03 gmc 2500 hd im having headlight problems but only sometimes and only when i have to high beams on and I have to switch to low beams the low beams don't come except when you hit a bump in...


Replace the headlight dimmer switch on the steering column and check the connector to it fro signs of overheating, replace connector and switch as one repair. Do not use crimp connectors, solder all wires as needed and use shrink tube to insult the solder joints.

Low beams stopped working high beams work fine


Either both bulbs are bad(I've seen it before) or your
dimmer/headlight switch is bad. If you can without pulling the bulb, pull plug from the light. If it's a 4 lamp system pull the low beam. Do this on the left side as the right feeds from the left. With a 12v test light, check for power. (with lo beam on) if you have
power, change the lamp, if you don't it's most likly
the dimmer switch at the steering collum.
Hope this helps Good luck

Low beam head lamps don't work


From cheapest/most likely to more expensive: Replace fuse; Replace bulbs; Replace DRL Relay; Check the Ground/Low beam wires for shorts or cuts, Replace Headlight control Switch. Also make sure to check the dimmer relay, its easy to tell if your relay is bad, they will buzz and get hot if defective

2002 pontiac grand prix gt. High beams are dimmer


A loose ground wire to the headlight will keep it dim,Or a headlight adjustment will bring the headlight up.If you can have your headlight turned on a garage door or something at night,and then watch as you change your headlights from low beam to high beam which ones are higher.the last thing to verify is that your high beam headlights are not the plastic lens type that turn dull which cuts the light power.

94 dodge intrepid no low-beams


It could be a dimmer switch. Although make sure both Head light bulbs aren't burnt out. Check for power and ground at the low beam headlight connectors.
