I'm having windshield wiper problems and need to remove the heater blower to access the wiper assembly. After I removed the blower cover, I haven't been able to get the blower motor out. I noticed a metal strap across the center of the blower motor. Is this what is holding in? Any help would be appreciated. The actual wiper problem is that the wipers will rotate about 10 degrees up and then hang up. If I bump them with my hand, they will finish their motion and hang then up at the same spot. I am assuming my problem is in the linkage or the transmission.
