Hi everyone!
I have a '96 Explorer 4.0 that I discovered that the front wipers and washer do not work. I live in SoCal so it is not frozen with ice or blades are stuck to windshield and since it is SoCal there is not much rain right now. I just happened to turn my wipers on and nothing happened! I have checked the fuses with my Ohm meter and they were good. I checked the fuse box and I am getting power to the fuses. I checked the relays under the hood and they seem to be okay. I switched the relay for the horn and wipers and horn worked with all three relays (Wiper run, Wiper hi/low. and horn). I tried to test the wiring harness and I am getting constant power when key is on and tried to test the other wires, (bl/o, w, blk, red, bl, blk) and I was not getting much of a reading from the rest, with or without switch being in run or intermittent. I was testing with a resistance setting on my meter. ( I was following someone else's instructions on how to test the harness). I came to the conclusion that my switch (MFS) was bad and pulled it out and tested it. The book I have gave instructions on what prongs to test with my meter and I came up with a negative on the switch so I replaced it. No luck! What the book did not tell me is that I needed my meter on not on continuity but on 20K or even 200K resistance setting. My old switch is good.
I am at the end of my rope trying to figure this out. If switch is good, fuses and relays are good, then what? I even went as far to take motor off but I am not sure how to test the motor. I know I was getting constant power but nothing out of the others. The two black wires in the harness are grounds and as far as I can tell they are grounded. I believe that the front and rear washers work off the same fuse and rear washer works.
I would really appreciate any help with testing motor and harness and fixing this problem
