Reply to "No Back up lights"

First, you really need to determine if there is voltage coming off, or even going to, the back up switch. Then find out if it is making it to the wiring harness at the tail light housings. Get a test light, or voltmeter and find out.

Sometimes the lamp sockets, while appearing solidly mounted in the metal strap that runs the full width on the back of the housing, develop a corrosion that prevents the grounding portion of the circuit from getting to the lamp. This is an internal corrosion and may not be readily visible. Take an ohm meter and check for continuity between the strap and the socket.

If not there, try twisting the socket to break free from the corrosion. Second technique would be to use a sharp awl or center punch and hammer some indentations in the socket ring, where it is crimped into the strap. Use a proper size socket to provide a back-up so you don't damage the plastic housing.

Try these tricks before spending money on a switch that you may not even need.
