Why would your high beam work and not low bean in 1999 ford explorer?

Possible Causes:

1. Headlight Switch Failure: The headlight switch may be faulty, preventing the low beams from turning on while allowing the high beams to function. Try wiggling or pressing the switch to see if it makes any difference.

2. Headlight Relay Issue: There might be a problem with the headlight relay, which controls the power supply to the headlights. Check and replace the headlight relay if necessary.

3. Bulb Problems: It's possible that the low beam headlight bulb has burned out or has a loose connection. Inspect the bulbs and their sockets for any damage or poor connections. Replace the bulbs if needed.

4. Wiring Issues: Faulty wiring or a damaged wire could be causing the low beams not to work. Look for any exposed or damaged wires near the headlights and repair or replace them as needed.

5. Fuse Issues: A blown fuse can also cause the low beams to stop working. Locate the fuse box and check the fuses related to the headlights. Replace any blown fuses.

6. Faulty Headlight Assembly: In rare cases, the entire headlight assembly might be defective, leading to the low beam failure. Consider having a qualified mechanic inspect the assembly to determine if it needs to be replaced.
