check relays under the hood Answer It could be the switch on the dashboard.
Possibly a bad headlight switch or connector. I just had a `93 Sable that the headlights would turn off when the right indicator was selected, and come back on as soon as it turned off. The signal/wiper switch was in rough shape (washers didn't work and wipers only worked on high) so I changed it out. headlights still shut off on right turn signal. Pulled the dash and found the headlight switch over heating, and connector melted. Replaced connector and switch. SOLVED...
Your low beam headlight bulbs are probably both burned out.
If fuses are good, I'd check all bulbs on that circuit. Take note that many vehicles have multiple lights on one circuit. Start with the parking light bulbs though. Don't forget license plate light and trailer hitch harness. If it ends up being a bad bulb, see sources and related links below for bulb information.

AnswerIf the bulbs check out OK then I would check for a loose ground wire.Replace your turn signal switch, that's what I had to replace to get mine working again.

You have to diagnose the system to determine the cause. Check the fuses, the bulbs, the flasher relay then the switch.

Working brake lights are important for safety reasons while driving. It is important to check all of the wiring, if the brake lights are not working and the fuses and bulbs have been checked.
