Rear wiper doesn't clear outer-most third as if there's insufficient pressure

[dug dog]

Anyone else notice this? It's a pretty short blade and I'm getting only roughly 2/3 of what it should clear. I thought that there might be a problem with the spring in mine, so I just replaced it with a used one from the wrecker and it's no better.

Here's a shot of the wiper arm mounted as far as I could get it on the motor spline. Does this look right? I thought it should be up tight to the glass but there's no way it's going on that far.

How do you pull off the cover? I can look at mine since I get full wiper-to-window coverage.

The cover just pulls off...My wiper leaves about an inch at the very top..I chalk it up to inadequate spring pressure on the blade. It's not enough to bother me...

This thread doesn't address that specifically but it can help..

Aftermarket???

I can't explain why nut mine usewd to that. I removed the aftermarket wiper and bought a new one from Mazda (OEM) and everything worked fine after that.

On our's I had to do some grinding of plastic to allow it to move enough.

Yeah I pulled the plastic off - the assembly stands proud of the window about that much. +1 on the aftermarket blade being at fault.

I had the same problem when I replaced the wiper arm after the rubber fin got streaky. Fortunately I kept the old arm. The new one didn't touch the outer 1/2 of the glass in its span. I tightened down the bolt but that made no difference. I removed the replacement arm and attempted to bend a curve into the plastic. I broke the arm. I got my old arm and carefully put the fin from the new arm into the plastic of the old one. It works like a charm.

OEM is the way to go...for some reason

I actually came here a few days ago to look this very problem up. I too had put on an aftermarket blade. When my wife brought it in for the Recall repair I told her to buy a rear blade based on responses above. OEM blade works perfectly.

I had this problem a few months ago and Mazdas247 helped me out. Only the OEM blade will work. I was also told that when replacing it next time to just buy the rubber and cut it to fit.
