I have a 04 f150 and my reverse sensor button will not turn on...?

 

No idea what you are talking about....are you saying the reverse lights do not light up? What is a reverse sensor button supposed to "turn on"?

There is no such thing as a reverse sensor button. There is a "reversing lamp switch", located on the left (drivers side) of the transmission, also refered to as the Digital Transmission Range (DTR) sensor.

 

actually he might mean the reverse parking sensor button wont turn off the sensor cause by pushing that button it turns off the sensing so it doesnt beep. its on when you turn on the truck.

 

It always helps when folks provide a bit more information. My wife always calls me a know it all, but this proves I don't.

 

i replaced a fuse and corrected mine. but its off again i just havent had time to replace it
