My backup lights suddenly stopped working.
I checked the fuses and replaced them anyway.
I checked the bulbs and they both work.

It's a manual tranny. Is there a reverse switch that's gone bad? What else can I check? It's a 2001 4x2.
Thanks,

Yep there will be a switch on the trans.

I'm going to check the junk yard. Is there a way to check these switches with a multimeter?

I have the same problem in my 98 1500 laramie 4x4. Mine is an automatic though. Is there still a switch and where would I locate it?
