Customer Question

I'd like to remove the rear wiper arm. I took off the nut, expecting the arm to come off and it did not.
JA: Have you checked the fuses? Do you know if there is power to the wiper motor?
Customer: The reason I'm taking the arm off is that I have a bike rack I install. Then, if the rear wiper accidentally is turned on, the fuse blows and the AC goes off. To prevent that, I thought I'd remove the arm.
JA: What is the model/year of your Mazda?
Customer: It's a CX-7, I believe 2010
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: I've just taken off the casing, then the lug nut. But the arm doesn't come off. I thought of forcibly turning the arm, to the left but I'm afraid to break it.
JA: Anything else you think the mechanic should know?
Customer: No, I don't think so. The wiper works fine when the fuse is OK. The problem is that it can hit the bike rack when it is installed, and then the fuse blows.

Hello, I'm Brandon - mazda tech.

The rust and dirt is holding the arm in place.

You will need to spray some silicone or WD-40 soak the thread.

After 5 minutes of so then pull it out with your hand.

If your finger can't pull it out with a plier. Let me know if you have further questions.
