Why do my low beams not work but high beams do?
Headlight Fuse or Relay is Bad Like all electrical systems, the headlights in your vehicle have a fuse in the circuit to prevent too much electricity from reaching the bulb. There will also be a headlight relay that switches power from the low beams to the high beams.
What is a bad relay?
One of the most common symptoms of a failed ignition relay is a car that suddenly stalls while operating. If the ignition relay shorts, burns out, or otherwise fails while the engine is operating it will cut off power to the fuel pump and ignition system.

Can AutoZone test a relay?
A relay can be checked with a jump cable, a voltimeter, an ohmimeter or a test light. If the terminals are accessible and the relay is not controlled by a computer, the fastest method will be a jump cable and a test light. If the voltage is not present, the relay coil is defective.
Where is headlight relay located?
