 Does anyone have a windshield motor pump for a GM 4104?

There is no pump, it runs off the air system.

Ok, what is it called? A regulator? My drivers side one doesn't work the air inlet cracked and broke

Do you mean the bit that flaps the wiper back and forth?  It's the windshield wiper motor.  You could also mean the windshield wiper control, on the dash, that regulates the air flow to the motor.  If you mean a pump, you could mean the air pump thingy that is inside the washer bottle that holds the fluid.  It has an air regulator control on the dash too.  So you could mean about 6 different things...  They all run off air pressure.

 I mean  "the bit that flaps the wiper back and forth?  It's the windshield wiper motor."      My bus doesn't have windshield fluid shooter outter thingy....lol

If you just broke the air line connection you can buy those without buying the complete motor fwiw

Luke at U S Coach has many of the parts you will need to fix your bus.

There were two different motors and controls used on the 4104, Trico and Sprague.  I think the Sprague was for the pantograph wipers and Trico for the standard, but I'm not sure.

Mine are Air Push rebuilt them and still don't work, next replace the control valve$.

Air Push is a trade name for Sprague same motor

Make double sure it isn't the switch/regulator.

Those things failing have caused a lot of motors to be replaced!

I repaired one but don't remember how I did it, just that it wasn't very easy.

Next time I'll just substitute a plain ole air valve and be done with it. The plumbing is a real PIA and has oddball fittings.

 Mine says "Air Push" on it. It wasn't the air line that broke, but the plate with the threads in it that the line screws into that broke. Im trying to upload pictures from my phone that shows it, but having trouble.

 That link is to my windshield motor picture. I couldn't get it to upload here? It is a blurry picture, but it you look closely to a copper line just to the left of the yellow line. you will see what broke.
