I have a 1994 Ford Ranger with malfunctioning wipers.
At first the symptom was the wipers would not turn off. I thought the issue to be the MFS (multi-function switch), after replacing it from another truck I was told was compatible at the juk yard counter the problem was still not resolved, so I replaced the wiper motor. Now the wipers do not turn off and sometimes they don't turn on either. I've tested the relays (but i don't think a relay controls the wipers in this model). Even though the weird looking 6A fuse passes a continuity test, I have seen another post [1] that suggests this was the issue for them so I have ordered one. I saw in another post [2] that mis-matching MFS and wiper motors is and issue, so I am concerned about this as well.
I'd like to troubleshoot this issue more intelligently. I am new to wiring diagrams for vehicles. Can anyone point me in the right direction of understanding how to trouble shoot this component that does not involve changing every component until it works? Also what references should I be using if the Haynes manual is insufficient?
