M923A2 Wiper Motor

[FastFred]

Newb here... Air leak out the front of the wiper motor. Fixable or must be replaced?

 

[dawico]

When does it leak? All the time or just when you use it?

I assume it isn't just the air exhaust when in use, correct?

I haven't had any issues with mine (yet) so I am not familiar with the symptoms.

I was surprised how loud they hiss when running. I thought it was a major leak, then figured out it's just the way they function.

-m923a2 has a passenger side wiper that after losing air pressure it drops down anyone ever heard of this or possible cause

My driver side leaks through the exhaust 24/7 when there's air.

Like yours, my pass side drops own too.

A small engine fuel filter or sintered air muffler/filter on a short hose on the air wiper exhaust can silence them by 90% with no loss of performance.

Pull your wiper motor motor hoses off and squirt some air tool oil in there and then run them. It may be all they need. Valve may be suspect also.

Oil them as said above and try pushing in the button, if it is stuck in try pulling it out. I like converting to electric system off M35A3.
