Well, my rear wiper/sprayer has decided to go nuts. A few weeks ago I noticed that the sprayer started to follow the wiper. Result: the entire right side of the boot gets sprayed, starting from the center of the glass around 180 degrees to the center of the license plate.

Fast forward a couple weeks and now my wiper decides to stop at various positions other than the "home" position.

Any ideas or suggestions? Am I looking at a new wiper motor or could it be a relay problem as well? I'm thinking wiper motor since the sprayer is acting up too. Any suggestions for troubleshooting?

 

Just a guess here, as I don't have the wiper/sprayer handy to view first-hand - is the nut on the shaft tightened properly? If it's loose, it could allow the wiper to slip the spline and park in odd positions, and it may be responsible for holding the sprayer steady as well.

Again, apologies if this is inaccurate info. But your description of the symptoms suggest a loose nut.

Cheers,

Spridget

 

The rear wiper motor is look like this and the spline part pivots while the sprayer stays stationary. sounds like the shaft and the spray head are disconnected and sliding in the unit shell. First it was the spray part , not the whole shaft. Looks like the motor / sprayer. You can try to tighten down the nut, first and see it that helps. But the sprayer being all over the place sounds like the shaft is broke. See below to help.

Thanks

 

Thanks for the replies.

The nut was definitely tight. I soaked it with PB blaster for a few minutes and was able to get it off. Now I soaked it again because the arm is frozen to the shaft.

A couple things to note. First, the sprayer part moves freely, not easily, but I am able to turn it. The wiper arm resists turning if I try to turn it. Second, I noticed the wiper arm is cracked by the shaft but it does not appear to be slipping the splines since I cannot turn it freely. Third, I removed the panel from inside the boot and noticed the inside wet with wiper fluid. The hose is intact and it appears to be leaking internally inside the motor and leaking from the seal between the shiny metal shell of the motor and the black plastic mount.

 

Thanks for the picture,

Looks like its damaged a bit on the internals, multiple issues going on. I would say to replace the motor which includes the shaft and nozzle. If you can save the arm to attach to a new one, if not i have the parts linked above. I would guess the reason it spins is that the nozzle is separate internally from the shaft and thus when spray pressure is applied leaks behind the trunk interior lid, leaking internally inside the motor.

The motor sprayer is one unit, so there are no other part number for the sections.

Thanks and hope that helps.

 

Very helpful, thanks. Do I need to replace the grommet too once I take out the motor or can it be reused?

 

You are welcome.


The grommet should be ok, unless its torn or when up pop it out its brittle. Also prevents water from the window coming in.

Thanks

 

Unless it is easy to replace and easy to see any leakage, I would just replace the grommet while I was in there. Unless the part is really expensive, at least.

 

Yeah, I think its a no-brainer to just replace it while I have it apart. It doesn't leak now, but I know it will if I don't replace it.


ECSTuning,

Thanks a bunch. Do you happen to have the part # for the hinge cover(#4 in diagram). I'm concerned that if I get a new wiper arm, the color wont match the hinge cover due to fading.

 

#4 part cover comes with the whole arm #3, Check out the picture, unless I am missing something you are talking about?

What is part of the arm and the old one might show the discolorness of the black trim is the rear wiper blade, its part of the arm, you can see it snaps on and the one half of the blade armature is designed into the piece. The factory MINI one has no brand on the top, the aftermarket ones are the same just say Bosch or Valeo. But the same design. Completes the look.

Also, Check your blade while you are back there, if its worn or torn since you are back there it might be a good thing to replace it. If tron to much it can etch the glass.

Thanks

 

Thanks. I'm good with changing wiper blades, I would never let a blade get that bad. Once it starts streaking, it gets replaced.

The reason I asked about the hinge cover is it's listed on realoem,com as a separate part, wiper arm cover Part # 61627129282. So it's included with the wiper arm but also sold separately? I'm about to place my order now, so I just want to confirm that it does come with the wiper arm.

 

Great, just wanted to let you know what all comes with it. The pictures help explain things.

Yes, comes with the cover 61627129282 , but also sold separately encase you lose or damage it.

Thanks again.

 

Just want to give two thumbs up to ECSTuning for all the help with my never ending questions. I ordered on Monday and received everything via USPS Ground on Friday, even with the July 4th holiday being on Thursday. Total price for motor, arm, blade, grommet, nut, and shipping was cheaper than just the wiper motor from the dealer.

I have it all assembled and it works perfectly. Now I just need to figure out my driver side window dipping problem and I'll be loving my MINI again.

 

I'm experiencing the exact same issues as you've described Jlobb2. The crazy rear wiper stopping at random positions, and the leak from between the metal shell on the motor and the black plastic mount. I will contact my dealer tomorrow to hear what they come up with as a solution...

 

minMINI - its most likely the same issue. I bet its the motor also. You have the parts above to DIY it yourself.


Jlobbs2 - You are welcome. " Now I just need to figure out my driver side window dipping problem " Most likely on that its the points for the window dipping when you open/ close the door, it needs reset, to relearn the points. I think its 15sec hold down button, 15 hold up. Then tapping it up and down. Otherwise the dealership can reset it.

 

Thanks. I've tried the 15 sec down/up with all the variations I can think of but still it's totally random. It will work fine for a few days, weeks, months, then not work at all for a few days or weeks. It doesn't matter if it's cold/hot or wet/dry. It's totally random.

I've had it at the dealer a few times, paid for the electrical system diagnostic, and they told me it was the door lock actuator and possibly the window motor. I replaced the actuator about two years ago and that really didn't solve the problem, unless it's gone bad again in that short of time. I'll try replacing the window motor once it warms up a bit.

The strange part about the window is that sometimes when I open the door to get in/out, the window will dip down and back up while the door is already swung out. I can swing the door in and out and the window will sometimes repeat the dip down/up but just not in the same spot. Sometimes it will do it at quarter open, sometimes at half open, and sometimes near full open. Most of the time it just does nothing.

 

Its triggered by the door lock , when you open the door, to dip. Then the motor dips it down , then when you shut the door it goes back up. Sounds like a door lock that is weird, if you already replaced the motor and had a MINI tech run the computer for electrical faults.

That's what I would replace if everything else is fine.

Here s a link to the door lock diagram and parts for the R56.

Thanks

 

So you still think it's the door lock actuator, huh? Argh! I bought a genuine mini replacement so I thought it would last more than 6 months or so. These things are not cheap either if I need to replace it more often that the windshield wipers.

I need to figure out how to test this door lock unit. I barely drive the car at this point because when the window doesn't dip, I'm afraid it's going to shatter when I close it. The dealer wanted $500 or $600 to replace the door lock and recommended I replace the window motor too while they have it apart for another $300. They said there could be a dead spot in the window motor that could cause the problem too. I don't buy that because the window works normally otherwise.

Once it warms up I'll take it apart again. I wonder if there is a break/short in one of the wires since this is such a random event.
