Low Beams Don't Work!

Low beams quit working but high beams are working, fog lights work and markers work, except for one vertical on one side on 2002 Chevrolet Trailblazer LTZ, is it the relay fuse?

    i have the exact same problem. check the fuses and they are fine. the dealership said to check the bulbs but offered nothing after that. it is hard to believe that both bulbs would go out at the same time.

    Found the problem - it was the relay fuse either it was #45 or #46 not sure but both those fuses are the same so if you switch them around you'll find out quickly whether or not this was your problem - had to buy the part from the dealer though $$$$

Is there any fuses or relays that are not in the fuse box on a 2002 buick rendezvousfor the bright lights


The high and low beam lights use the same power source, so if the low beams work the high beams have power.
There is a low and high beam relay controlled by the dimmer switch.
If the low beams work and the high beams don't, and the bulbs are good, check the dimmer switch and the high beam relay.

Low beam head lights don't work 1999 Lexus LX470


Don't forget to check the Relays.... Black boxes associated with the fuses... Also there are usually two fuse blocks ONE inside of the car on the drivers side: Under the dash, or on the side of it. TWO is under the hood in the engine compartment area either on the firewall or on one of the fenders usually close to, same side as the battery.

Low beam dont work


usually both lights don't go at once so it is probably the resistor on the same circuit, probably just a fuse or relay! get a wiring diagram for illumination and test the circuit with a DVOM, bet you just have a bad connection, or loose wire, bad relay.....
