1995 2500, Headlights irradically blink off momentarily. sometimes JUST the radio time display will come on real bright . like 'Christine' in the Fury ,
all gauges still work fine,normal gauge lighting unaffected.any help appreciated. DAVE

 

Hello, sounds like your headlight switch is going bad to me. I had the same problem with my headlights but the radio lights were unaffected. My problem was the multifunction switch on the steering column though . So thats why i say it's the headlight switch on the dash. From what i hear it's a pretty common problem.

Does it happen when you 1st start the truck, when its cold out. Cuz if it happens then, then its your grid heaters warming up. I asked about it too.

If not, then I'm not sure, unless you are drawing power from your batteries (stereo system, ect..)

Good luck,

I'll 2nd the light switch diagnosis.

 

Thanx guys , It's not the grid heaters I'm used to that . i believe it is the headlight switch once i got a chance to wiggle everything I can make it do it at will. I actually had a guy pull over in front of me tonight on the way home. maybe I'll leave it alone:-), DAVE
