I have a 2000 D2 (second owner) the off-road lights only came on briefly then went off, the light on the switch also went off when the lights turned off. I turned the lights on a second time and they again turned off after a few seconds; now the lights will not turn on at all. I attempted to locate a relay for them, but was unable to find one marked for them (however all the other lights are marked, and they all work fine) Any suggestions for troublehsooting them?

 

multi-meter and start tracing

 

If you are talking about the factory off road lights, look in your owner manual for the relays location, or look inside the 2 fuse blocks, there should be a label showing what you need.
