the low beam headlights on my 95 cherokee stopped working a few days ago (at night in the rain....). Anyway, here's the situation: The high beams still work, not the low beams. One of the lights has flickered on and off sometimes, so i pulled it out and found that the contacts were really corroded on the wiring harness. Replaced the sockets on both sides. Same problem, the high beams work, but not the lows. Took off the dash, and pulled out the connector for the "multifunction switch." i tested the pins on the connector and found one that always was hot for the high beams, and bridged it to the hi ground next to it, and the highs came on. Found the pin for the low beams, and when turning the dash switch on, it goes to 12. however bridging that pin with the ground next to it does NOT turn on the low beams.
So i surmise from all this that
1. It's not the grounds, as the high and low have the same ground pin on the lamps
2. It's not the headlight switch, as the voltage on the connector changes when you turn it on
3. It's not the multifunction switch, as bridging the connector does not make the lights turn on.
So it's somewhere between the multifunction connector and the lights.... but what is there??? other than it being a wire cut, is there a relay, or a connector, or anything else in the path? the wiring diagram in the haynes manual shows nothing.
