Hello I have a 1997 Clubwagon XLT 12 passenger. (Econoline 250 5.4ltr).

I am having a problem with my hi beams. All lights work except when I try to turn on my hi beams. My hi beam light on the dash does not come on and it looks like the hi beams go from regular lights to the parking lights.

Parking lights work. Regular driving lights works. Pull switch lights dim to parking lights.
Any ideas?

Thanks in advance Robert
