2004 Mazda6 Wagon Rear Wiper Motor
Looking for some advice or words of wisdom... I had a bike rack strapped tot he back of my wagon all summer. At least 3X, the rear wipers got turned on and of course, the arm stalled out when it struck the bike rack. Once I did it and caught it and turned it off right away, the other time it went several hours before I got home and found it switched on (wife was complaining about a "hot" odor, go figure!) Anyway, now something is wrong with the motor. At first, I thought it was a fuse so I checked and the specified 10 amp fuse located in the kick panel on the driver side appears to be good.
When I turn the wiper motor on, I can hear a noise like it is trying to work. If I get out and assist the wiper arm, it will swipe back and forth. If I lift it off the glass, it will also swipe. If I leave the arm down on the glass, it won't swipe and makes the noise.
Since the arm swipes if I assist it, I have to gather that all the connections, power, etc. are working. My question is "Do you think the motor is shot?" If it is, how hard is it to replace? I assume that I will have to remove all the inside panel to get at it... If you think the motor is still OK, what might I do/try to get it able to swipe the arm? Could a nut have loosened up or something when the arm stalled out on the bike rack?
Thanks for any thoughts or words of wisdom!!!
