Weird Electrical Problem...wipers,headlights,fan....
For some strange reason today without warning the ac fan cuts offwhile on highspeed, along with the windshield wipers(not being used at the time).I went to checking all other electrical items and found that headlights would not come up however signal lights appeared to be fine.Two miles down the road all of a sudden everything is back to normal.Could this be a grounds problem?...is so where would I start to resolve it?..or possilbe relays.Kinda hard to find the problem as it has only did this twice and came back on before getting home.We haven't experienced any other type of electrical problems other that the original Blaupunkt radio went on the blink a week or so ago but have replaced it already with a Kenwood that works just fine.

You have a power bus problem caused by relay G14 or your ignition switch.
Whenever your ignition switch is in postion 1 (accessory) or position 2 (on), Relay G14 (the Kl X relay) provides power to the Kl X bus in the fuse panel. This bus in turn provides power to relays for equipment that only runs while your key is on (headlights, wipers, heater blower fan, etc.)
Next time it happens, pull relay G14 and jumper between socket 30 (unswitched power from the Kl 30 bus) to socket 7 (Kl X bus.) Your accessories should now work whether the key is on or off. Check to see if you have +12 V at both sockets 30 and 5. Assuming you do, now check to see if socket 6 is grounded with the key on and open with the key off. If socket 6 is grounding, then the problem is your relay. If socket 6 is not grounding, or intermittently grounding, the problem is your ignition switch, or Sid's grounds.

Actually, I meant "check your grounds, as per SidViscous's advice." I mean, if we can't trust your grounds, Sid, whose can we trust?

Thanks for the info guys....I'll try and check it out first chance I get.This isn't my daily driver so I have some time to work with it.But I doubt very seriously I will be driving it at night or on cloudy days until I find the culprit!
