In this video I diagnose and replace a rear wiper motor on a mercury Mountaineer. It would be the same process as a ford Explorer. The nut that holds them on the glass can be a real pain in the... well you'll see. -Enjoy!

    Hey Eric…thanks for this old, but still very useful video!! Question I have is that all voltages are ok except for int 1 and int 2 (2007 exploder doesn't have constant on). Those two voltage read 0.2 volts?! Checked fuses in passenger cmpt and under hood as well as the relay under hood. Any ideas? Try to hot wire motor to confirm that it's wires? Thanks in advance.

    awesome plate

  3. Avataaar/Circle Created with python_avatars John Mullen says:

    I have a 2016 Ford Explorer. The rear window shattered for unknown reasons. A local glass company replaced the glass but now when we turn on the rear wiper and off, it will stop in different positions. We have to turn it off and on several times until it happens to stop in the parked position. Is that a faulty motor or something else? I'll gladly buy something from your swag shop if you can point me in the right direction. 🙂

    Ask your wife how to do it – she did it in a few minutes in another video 🙂

    It’s always the motor I’m on my second one in 3 years… I love my exploder sooooo much

    Ms. O TAUGHT YOU WELL

    Hoping you could help me out. I am working on installing a rear wiper motor out of a 2008 explorer in my SxS. I’m trying to wire it using the control module and with the the help of your video I was able to figure out the wiring. The wiper works as it should expect when I ground the on position wire, the unit goes into the wash mode. I am assuming the module is looking for a resistance to ground of the on position and no resistance for the washer cycle. I haven’t been able to find a wiring diagram and was hoping you could tell me the resistance value so I can purchase the correct size resistor to make it work. Thanks

    Another great video,thanks.

    i know you can dooo it mr eric great work again 😉

  11. Avataaar/Circle Created with python_avatars Mitch Quick says:

    Great video. I like the fact you show it right from the beginning especially with the encountered problems. You had more trouble than I did with the nut, made me feel better. lol Now I have to see if you have a video for my '07 Explorer Temp blend actuator. Fingers crossed, it's getting colder.

  12. Avataaar/Circle Created with python_avatars smitty1952 says:

    So Eric, did you get the SMA license plate idea from Diagnose Dan?

  13. Avataaar/Circle Created with python_avatars Joe Wurzinger says:

    It's pretty ridiculous when you constantly type in what you looking for an you constantly get bullshit that has nothing to do with what you requested. Utube sucks

  14. Avataaar/Circle Created with python_avatars Stephen Erickson says:

    The scariest video you have ever produced

  15. Avataaar/Circle Created with python_avatars Cal Brown says:

    And using a screwdriver as a drift, you have lost respect for tools for the sake of expediency.

  16. Avataaar/Circle Created with python_avatars Cal Brown says:

    Tsk, you were trying to use the adjustable wrench backwards. You know better.

  17. Avataaar/Circle Created with python_avatars Sam Rugtiv says:

    Well done Eric.

  18. Avataaar/Circle Created with python_avatars Virginia Preast says:

    My rear wiper doesn't work. The arm is all loosy-goosy and just hangs straight down. I can hear the motor try to engage when I turn it on. Could it be the motor or a different issue since it doesn't even stay up on the window?

  19. Avataaar/Circle Created with python_avatars Geo economics says:

    Air hammer

  20. Avataaar/Circle Created with python_avatars wakcedout says:

    In my saved pile since i have an 08 ford explorer doing the exact same.thing and i need to replace the bugger lol

    It always seem like someone is always cutting grass when you have the bay doors open.

  22. Avataaar/Circle Created with python_avatars Mark Wolf says:

    I had to let my expedition soak with some pen oil for like a day with the window open just to get that nut off. I live in a Salt State too man. It sucks. I just cleaned up the shaft on mine and antisiezed the shit out of it. If only ford used sealed roller bearings for this instead of a shaft and brass bushings.

  23. Avataaar/Circle Created with python_avatars Chaos.Mtndew says:

    what puller is that ive been working on my 05 caravans front wiper arms for 3 days now using the wrench under and haming on the nut to try and break it looste a whole can of penetrating fluid and still nothing

  24. Avataaar/Circle Created with python_avatars Mejia C says:

    I wonder if you can test that wiper motor direct with the power probe?

  25. Avataaar/Circle Created with python_avatars Danny Hubert says:

    Eric when your you tube video

  26. Avataaar/Circle Created with python_avatars William Smith says:

    Eric call wife she job done

  27. Avataaar/Circle Created with python_avatars DieEule says:

    I cut the nut off with a Dremel since my replacement motor came with a nut. Hope that helps others.

    Feed her taters Eric I wanna see some glass flying

  32. Avataaar/Circle Created with python_avatars Jay Lopez says:

    That’s was a job for “big nasty” 😂

  33. Avataaar/Circle Created with python_avatars James Farnham says:

    You really epitomize the need to constantly be thinking and paying attention to what's happening all through the job. The chance that you are often redoing or chasing someone elses job before you get to it requires a wider scope in the thought process. Those metal grommets were a prime example…one was one way and one the other. Good logic with the blend of intelligence and mechanical thinking applied. Excellent work Eric, love these videos!! Thanks for all you do!. Jim.

  34. Avataaar/Circle Created with python_avatars ncrdisabled Submarine vet says:

    I have broke the glass

    You are really great at your job! We need more mechanics like you in the U.S.

  36. Avataaar/Circle Created with python_avatars John Alexander says:

    Changing the name of your shop to “ All GIrl Garage” ….. LOL

  37. Avataaar/Circle Created with python_avatars Mike's World says:

    No need to worry about twisting the studs off the glass when tightening. If they twists off, just back off 1/4 turn and your good. Also I can't understand why you worry about breaking the glass. If it breaks you can just rewind the video and it goes back together. My wife has a friend who needed a wiper motor changed on her caravan and i decided not to do it because with my luck the glass would have broken. She went to the university of YouTube and became youTube certified and did it herself and all went well for her. This was a great video, lots of suspense just waiting for the window to break. Glad it didn't for your sake.

    I was lookin' forward to a lil' love tap from the Big Nasty.

    Working on auto glass can be exciting! I once tried to get an old school cell antenna off the back window on my 79 Caprice, stuck on good. So, I turned the screw driver a touch sideways to pry it off and…..BOOM!….there goes my back window in a million pieces. Scared the hell out of me!

  43. Avataaar/Circle Created with python_avatars Martin P says:

    I'm still looking for that criticism and I'm going to find some😈 till next 🎥.

  44. Avataaar/Circle Created with python_avatars OldGrizzlyGamer says:

    One is gray with orange, and one is orange with gray. Sheesh, when working on a Ford, you have to think Ford. 😛

  45. Avataaar/Circle Created with python_avatars Michael O says:

    The other thing I've observed is a shiny new SOUTHMAINAUTO plate!!! You've got bigger Kahoonies than me Eric, I don't swing on those things with a dirty big long ratchet or go near them with a hammer & we don't even get the rust issues you have! My number one on those is go straight to the rattle gun, do not pass go, do not collect $200!!!

  46. Avataaar/Circle Created with python_avatars Mr B says:

    Oh man, lot of mincing about on that nut, big nasty would of tickled that off in nano seconds 😀
    Would need wait for glass repair for refitting though lol 😛
    Impacts can be pretty good on that sort of thing in light blips .
    Why they can't use nylon or brass nut I no idea & no new fittings on replacement motors can be a show stopper 🙁 .
    Job jobbed nicely mr O

  47. Avataaar/Circle Created with python_avatars allan mitchell says:

    Love the skills mr “o” big thumbs up 👍

  48. Avataaar/Circle Created with python_avatars Graveltrucking says:

    In AvE fashion tappy tap tap, sitting in my chair with the cheeks clenched tight waiting for that window to break. Impact gun works well when you need to torque off a nut but you can't use a ratchet or a bar because the leverage may cause you issues.

  49. Avataaar/Circle Created with python_avatars phonograf says:

    Next time make sure you grab the metric adjustable wrench rather than the SAE (American) one that you picked up. That way it will stay gripped when it pops. 😉
