my 2004 f150 super crew back up lights and reverse sensing system is inop. fuse is not blown and light bulbs have been replaced. any ideas?

 

Steering column reverse sensor switch, (same thing like the brake peddle switch) but it is located by your selector lever jut a WAG.

 

What or where is the WAG. My back up lights don't work either, same conditions.

 

A WAG is A "WILD *** GUESS"…
Have you checked for current, at the socket, most of the time the socket had ionization (rust) inside of it.

Stick a pin on the hot wire and see if you are getting any current.

I’m unsure on the F-150, but on some other models the contact point is on the shift selector lever. However I would follow the back up wires and see where the harness connects and try to check for current on the harness plug ins.

I would check the shift sensor as a last resort, also check the hot side of the fuse, to make sure you are getting juice to the socket.

Once more this is just a WAG……
