Plastic trim (black) on bottom edge of hatch, two screws hold that in inside the pill down handles, once that is removed three 10 mm blots hold the motor to the hatch, unplug the motor .... Done!!

I am willing to bet that none of the people in here have an actual blown or bad motor. It is the linkage that rusts and seizes up. I just fixed this 1 month ago.
To remove the wiper arm, use a gear puller as suggested already, or a special wiper arm removal tool. Princess auto has one for 12$ or so.
Remove the plastic trim on the inside of the hatch. There are 3 bolts or nuts IIRC that hold the motor and linkage mechanism onto the hatch. You have to take the plastic lid off the back of the motor/linkage housing to be able to access the linkage. When that is off, you might have to you a rubber mallet or a piece of wood and a hammer to take the linkage and shaft out of the housing. A bench vise is recommended but not needed. Some 120 grit sand paper and some grease. I use bearing grease for everything, but you can use whatever you have or prefer.
On mine, the shaft was not badly seized in the housing. It was the hinged/articulated linkage that was rusted. Take pictures/notes of how it is assembled, than pry it opened completely. Every piece comes off. Even though it looks like it's not. Sand every one of them until they are clean of rust, lube them up and put them together as they were and you will be surprised at how easy they move now. Fill the housing with grease, put the lid back on the housing, go to the car, plug the wire back in the motor and try your rear wiper. If it spins freely, you're almost done. Put the motor back in the hatch, put the trim back on, install the wiper arm and you're done.
Sorry I have no pictures of this. It's super easy to do and I think vortex or even here might be tutorials for this.
I would be curious how much a new motor/linkage is. And buying one from scrap is not worth it since all MKIV golfs are plagued by this issue. And even if you have your hatch replaced under warranty, they will not replace the wiper motor for free.

thanks for your input Doc Oc. it was the linkage assembly in the motor that was seized, however i mushroomed the washer nozzle in the end taking the shaft out of the housing.it was seized in there real good. I'm letting the link ass. soak in diesel fuel to help free up completely before reassembling. do you know if the shaft ass. can be bought separately in order to have washers again or would i have to buy a motor ass.? i can live without the washers....at least i should have a working wiper again. thanks

I'm not sure, but I don't think VW will sell just the linkage. You can ask on the forums and see if anybody has a busted one they are willing to give you or sell for cheap.
Is there no way to fix it? With a small file to go inside and clean the shaft?
I find myself using the rear washer way more than the front one. We have a lot of dirt roads around were I live.

no...the nozzle part is gone. had to hit the end of the shaft quite hard to remove link ass. from housing ...it's broken. i find that the rear window is a magnet for road spray. I'm satisfied if i only have the wiper working but the washer would absolutely would be a bonus.

I would miss mine dearly if I deleted it! Especially in the winter.

Remove the motor and take it apart, there are some electronics in there that switch the direction of rotation , if the sprayer has been leaking at the stem guaranteed there is corrosion and not functioning properly

Glad I found this thread. I just took my rear wiper linkage apart. I got all the gears apart inside, but couldn't get the entire shaft out of the housing. I cracked a bit of the black plastic on the outside of the shaft housing banging on it a bit in the process. I did spray anti-seize all over in there, and reassembled the gears etc. It works now.

But the spray nozzle still rotates with the rest of it.

I may just go buy a new one, or a used one and replace the entire thing.

At least I know how to do it now.

The wiper on my sisters Golf no longer works, because I'm the family mechanic, of course I get to fix it, lol!

I'm guessing the linkage is seized as well.

i replaced rear wiper motor last october....worked ok all winter. now every time i turn ignition on, wiper runs constantly for about 6 sweeps then stops at middle of window. checked at connector, my test light is on steady when plugged in to black(constant power) and green/red(signal for wipe). question....is there a module in rear motor to activate the sweep function, or is the intermittent ground signal supposed to come from somewhere else?

yvon, I know it has been nearly four years, but for anyone who may run into this issue, I would check into the green/red wire being grounded somewhere. I would suggest looking at the wiring that comes down from the top left corner as you face into the hatch from the back of the car.

That location is where I found my issue. I was perplexed for a while, when I grounded the green/red wire to the hatch, and the wiper would activate, but otherwise would not. When I looked into the aforementioned area, I saw that the green/red wire (and green/white wire too) was severed in two and sticking out of the rubber covering, which had gotten pinched somehow, by the previous owner. Once I soldered the wire back together, VOILA!, it was working once again. This was all after disassembling the wiper unit, cleaning, lubing, and general freeing up of the components. Since the washer tube is cracked, my guess is that it is the same old story of fluid getting into the unit and gunking it all up.

So, average person desperately looking for answers, there is something else to investigate. Clipped wires. I hope you find the solution to your answer soon.
