head scratcher...electrical

okay ladies and gentlemen...I have a good one for you.

problem - one out of every three times I switch from high beams to low beams, the low beams will come on for 1-2 seconds, then just shut off completely for 1-2 seconds and then come back on and work fine.
I have checked and cleaned the connectors on the lights - no help. I have wiggled every wire in the system that I can get my hands on, and played with the switch while the lights are on and it has no effect. I am getting good, steady current (~13 volts) to all three wires on both lights and it drops to ~0 when they (high/low beams) are switched on as it should. The tail lights stay on when the lights go out (????). According to the schematic, the problem is most likely in the red wire which goes from the "combination switch" to the "combination meter" and to each of the lights (if I am reading it right), or in the switch itself. I couldn't find the "combination meter" so I haven't ruled it out yet either.

ANY experience/advice/suggestions on this problem will be greatly appreciated.

If it doesn't do it all the time, that makes it hard to trace. Sounds liike a worn out switch or a bad wire (intermittenly shorting out).
Check your high/low switch, most likely thats the culprit. Good luck.

Do you have the daytime running light feature. If not I would say it is in the switch.

Mine used to do that too. I believe it was a faulty switch because if I flashed them from low to high enough times they'd eventually come back on. Luckily mine stopped doing it after a few times.

Sounds like a switch.

I agree the switch sounds like the problem you should be able to find them used for about $20.00 I think that was from trail tough but not shure when I was chasing electrical problems I scanned the wire schematic from my repair manual this alowed me to color the wires I was following on my computer and enlarge the whole thing so I could easily read it
