You might check to see if your front headlight bulbs are out.
Two lights from the front two at the back. i wish i could change that but there you go
Type your answer here... It could be the back up light censor. Depending on where it's located, you may have to drop the tranny. that could be where the censor is located. I had the same problem in my 1998 grand Cherokee and that's where it was located. the censor is about $20.
If the back lights on a Peugeot 206 are not working, make sure the bulbs are new. If the bulbs are not the problem, there could be an issue with the fuse.
check your ground wire in the back
Brake pedal switch, wiring, bulbs, bad trailer harness (if there), fuses...
I had the same problem with my 87 Riv. It was a burnt out bulb in the rear of the car. My front signals did work and as they run on different circuits, check and replace the bulbs. Access to the back lights are inside the trunk back.
Bad wheel bearing? Most likely a loose frt end component, Or the hub could be bent due to an impact.
It sounds as if there is a problem with the rear electronics module in the Ford Windstar. This controls the front and rear lights and it is located in the back in the cubby with the jack.
I have the same problem with my 06 Liberty. I think it has something to do with the trailer towing package as the problem did not occur until I noticed the lights stop working completely on my trailer.
On an average car, there are high and low beam lights for night driving, clearance lights on the front and back, front and rear turn signals, and back-up lights used when backing up.
That's a dumb question
Have you checked to see if your back lights are not burned out? That could be the problem. If your bulbs are good then you have a broken set of wires going to the rear lights, (look by where the trailer wiring was installed if so equipped as that's a common area of problem for broken wires. Hope that helps. i had the same problem with my 1985 south wind it had a exposed wire that ran right behind the brake peddle throw the floor Bord they did make the hole big enough so when the pushed the wire throw it striped it so every time i hit the brakes the fuse would blow. and i would have no lights. don't know if this helps you, good luck .
