Here's the thing. I ran into the same problem. I changed the blade, and my wiper was getting stuck. I bought a wiper removal tool, a spare arm and blade, a wiper motor, and the tiny wiper spray nozzle. Like in your video, my arm motor works fine when I lift the arm from the glass, but it gets stuck when it comes in contact with the glass. I changed the blade, but that didn't work. I used the wiper removal tool, which broke the arm from the nut. The upper bolt came off easily, but the arm was stuck. I applied WD-40 and other methods, but it wouldn't budge. So, I decided to take the arm off, but damaged the groove around the nut. Once that was out, I was left with the arm nut on the motor. I had to get some local mechanic help to remove it, which he did for free. I brought he car home and then installed my new arm and blade, but I ran into the same issue. I'm not sure if I need to change the motor, but when I lift the wiper arm from the glass, it revolves properly. I'm confused about what could be the issue. Any suggestions, guys? Although I have a replacement motor that I can install, I reckon the current motor is fine. If you think the motor is fine and something else needs to be checked, I will return the motor for a refund. I do get some click sound when I take the arm off the glass, which stopped when I changed it to the new one, still not sure what is it.
Whats do you do with a Grinder? All so to use WD 40? That is Not the Solution. You must used a hair dryer. When make the Part from the Viper warm for 5 minutes have a Easy Solution. Look is very quickly.
Good info, thanks! I have a 2017 Q5 and the arm broke. I got the bolt off, but the arm won't come off and as others pointed out, pulling to hard on it may break the wiper motor and then you are into more time and money. So I put PB Blaster on there and will leave the nut off and wait a day to see what happens. Also I just thought of an idea to lift the hatch until the bolt area is parallel to the ground and then spray penetrant in the area, so it sits like in bowl and let that sit for an hour. Just to see as others may not have cutting tool. Then get the Drimmel tool. Good idea with the cardboard. Note a Drimmel tool is smaller. Since the cutting blade is smaller I think I will cut it o n the side, so the cutting blade is parallel with the shaft. Then put a small screwdriver in the slot, tap it and the sleeve should spilt or open enough to relieve the tension and come out. If you don't have a cutting tool, a hack saw should work. Put it against the window with the blade facing down, and cut into sleeve until you reach the shaft. That is basically a relief cut. It will allow penetrant to get in there and if the cut slot is tapped with a screwdriver I think the sleeve will split.
I agree with you, save your time and use the a angle grinder as first option! If the shaft is stuck there no way to remove it without damaging mechanism, therefore the grinder is the best option.
I had to push a little to keep the wiper in the position I want, but by gradually tightening the nut, it fits into its seat and in the end it is tightened and ok.
What about the washer fluid jets? Did they work properly after your installation? I did not see you test that. And you did not show the insertion of the small plastic piece that directs the washer fluid out thru the plastic cover and out over the window. Just like the other video I watched. The job is not done UNTIL IT IS DONE!!!!
