i am not trying to insult your intelligence but it may be as simple as both bulbs burning out at once access the fuse panel and check to see if the headlight fuse is blown, in most cases since headlights use a lot of power they are put on their own circuit.
Most likely a fuse or a bad ground.
Fuse, wiring, bulbs
That car uses a single type 9004 bulb on each side of the car. The 9004 contains two filaments, one for low beam and one for high beam. If the high beams work but the low beams do not, then either the low beam filaments in both bulbs have burned out or there is a fault in the low beam feed circuit.
Check the fuses.
depends on which lights? inside over head? /Dash board?/Doors? /front headlights?/Flashers?/ turn signals?/ Backing lights?/ Parking lights?/ So which ones ? what Year??
if you've tried hitting the high/low beam switch & headlights are out on both, then a bad headlight switch or headlight switch plug or high/low beam switch plug not fully engaged.
Yes!
Check to see if you have a defective bulb. Turn signals/parking lights,and tailights a double filament, if one is bad (Both filaments touching) they will backfeed
a: you have a shorted filament in your turn signal light (arcing from turn filament to park light element, b: you have a bad ground at the headlight orturn signal associated with the issue c: you have the incorrect bulb installed in one of your turn signal lights d: most likely, you have a burned out bulb on one of the front side markers (these flash with the signals when headlights off using the ground plane of the parking light, as well they flash 180 degrees out of sync when parking/headlights on.
yes and no
It's probably time to replace your headlight switch. Had a similar problem on my '95. A new switch fixed her right up.
Check the fuses and the bulbs.
