Light Problem

I have a 94' 379 that the lights work fine on low. The problem is when I hit the high beams not only does the passenger side one not come on, but the low beam on that side goes out . Also the high beam indicator does not work. I pulled the bulbs out and checked the wiring and bulbs and all looked good. Changed a relay in the fuse panel and the lights and indicator worked briefly, not they don't again. Any ideas?

 

Check to be sure you have the correct head lights in the truck.sounds to me like wrong ones.

 

I think you might have a bad switch
