won't turn on...no kind of tapping or coaxing gets them to even flicker. headlights still work fine. that's about all i can tell you...anyone have any ideas as to why they'd suddenly stop after months of faithful use?
After checking the fuse :Brow: I would check the headlight swith itself to see if you are getting variable voltage when you turn the knob to dim the dash lights. Mine get a little touchy after sitting all winter until I spin it a time 'r two.
Could aslo be a bad ground. The headlights' system is seperate from the interior systems' I had the opposite problem last year, and found out just exactly why my horn relay would get triggered when I would hit the high beam switch...that was fun. I had just painted some things, and didn't scrape paint off a grounding point...so the headlight harness wouldn't work. I took out both the front and main harness and replaced everything, checked out the wires, didn't check the ground. I once accidentally shorted my cigarette lighter messing with my stereo, and melted the dash ground, and the lights wouldn't work. On my '70, the dash ground goes from a gauge in the cluster to a bracket just to the left of the steering column. It's quite close to the windsheild wiper switch ground, if I remember correctly, don't confuse the two.
Like Mike said, After checking the fuse (the iddibiddy 4A sucker) and checking that the knob didn't get turned (they dim ya know.. :gt: ) I'd go ground hunting.. Check the ground wire that's on the brake pedal assembly.
