high beam problems HELP!!!
ok this darn thing has gotten on my nerves,i have read threads till im blind and read wireing diagrams till i cant see straight.and i am no better off then when i started.heres the problem:
all of a suddon i notice the highbeam lights are staying on all the time when the key is on,when you hit the highbeam flasher the gas hand flickers.i have changed relays and unpluged switches,i have narrowed it down to a putple relay in the K9 position of the fuse panel(what the hell is it for???its not on my wiring diagram),when i pull this relay the head lights work normal again but then none of the damn gauges work,no gas no tach no temp no nothing,as soon as you plug the relay back in it all starts working again but the highbeams come back on again.
i have pulled the wireing harnes almost completly out of the car looking for burnt wires but it all looks fine.im worried this will burn something up....what does this K9 relay do???i have read on the eruo versions it is for rear fog lamps but those are not allowed here in the states.
i dont know what else to do ANY suggestions will be greatly appritiated.
I'd replace the relay first as mentioned, but the actual dimmer switch sounds suspect. Also physically trace/check your wiring (I know it makes my brain itch too...) but a lose ground lead and/or a melted or fused wire could give the same symptoms - especially on an "old girl" like yours.
