My reverse lights do not come on. I'v checked the fuses, the wiring and the bulbs and all are good. What else could it be?

I actually had to replace my rev switch to sort mine out. Climb under there and jump the switch while someone is checking your rev lights. I guess if you had a test light confirming you have power coming in would be your first step...but if not revert to previous plan.

 

can you tell me where exactly that rev switch is?

 

On mine...left side of trans..just above the pan, should have 3 wires going to it if I'm not mistaken. Yours should be similar.

 

Thanks, Ill check it out first thing in the morning.

 

Reverse switch is on the left hand side of the NV4500 near the back. There are 2 wires and a weatherpak connector...I just replaced one...this is most likely your problem.
