I have a 2001 Acura MDX Touring for my winter car. A couple days ago, I ran into some trouble with the driver side wiper blade arm.

The Passenger side works fine, and as long as the blade is removed from the driver side arm, it moves properly. When the blade is on the driver side arm, it moves a little (from the resting position), maybe a half inch or less, then stops as the passenger side blade then goes over it.

I'm pretty sure the teeth are shot, and obviously the motor is still good. I am looking for some help on what part(s) I need to get and replace. Thanks

The quicker the better. Time is definitely a factor with this weather this year!

 

Check the bolt that holds the arm make sure that is tight
