Headlights no Taillights

PERHAPS IT HAS A RELAY FOR THEM UNDER THE HOOD

more than likely it is going to be a short in the headlight switch. not uncommom.

The front park lights work correct? If the front park lights work than there is not a problem with the light switch since the brown wire from the switch supplies power to the front park lights, front side markers, and the rear taillights. There should be twelve volts on the brown wire from the headlight switch with the connector plugged in and the park lights turned on. If this is true that there is a problem with the wiring to the back of the vehicle. A thorough inspection of the harness should reveal the problem. The dim break and blinkers support the above. High resistance also know as corrosion, in the wires or connections would cause this problem.

The fuse is a good start. The headlight may also have a relay, which may be in another box similar to the fuse box. Check the fuse before the bulbs - it's more likely that a single fuse would blow, than both headlights blowing at once. the switch. Not sure where this is located on your car (dashboard? blinker column?) but that's another single point of failure that could explain both lights malfunctioning at once. check the fuses for the headlights, and the headlamp relay first. good-day !

go to an accredited auto electrician for electrical work
it may be a switch problem but I think that there is no power to the light relays ( switch or fuses)
if that model has a light control module , it could be that

They are called daytime runnig lights, doesn't you headlight switch have an "off" possition?

Sounds like a bad earth/ground. Check your earth connections.

Sounds like someone put the bulbs back in the wrong holes in the taillight. Or two wires are shorting together. Either way , I think if you remove the taillights , you will find the problem easily.

I was told that it is the rheostat, go to Advanced or O'Reilly's.

Look up under dash where brake pedal pivots, you should see a switch that is activated by pedal arm.
