Check the fuses.
Most likely a fuse or a bad ground.
Fuse, wiring, bulbs
It's probably time to replace your headlight switch. Had a similar problem on my '95. A new switch fixed her right up.
Start by checking your fuses. Then bulbs. Then switches in that order.
depends on which lights? inside over head? /Dash board?/Doors? /front headlights?/Flashers?/ turn signals?/ Backing lights?/ Parking lights?/ So which ones ? what Year??
Me too on a 2001 Sequoia. Drives fine, headlights, parking lights and dash lights work but that's it. Backup lights, air conditioner controls, all gauges, all indicator lights on dash all dead - all at the same time.
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
If you have no brake lights or tail lights then you've probably got an electrical problem. Check the fuses first and see if you have one or more blown.
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
