M-5 wiper motor

Our fire dept. has an M-5 and the drivers side wiper quit working. It has air to the motor, and if the hoses are alternately removed and replaced it will work, but it is difficult to do this while driving. I want to try simple first, and my thought is to spray some aerosol silicone lube into the air intakes. Should this work? any potential problems? I don't plan to chase this far with the air motor, because a replacement electric is half the money.
 
Add to some air tool oil to it. Years ago we kept alcohol to the air system and it kept things cleaned out.

Thanks, probably I should check for water in all the air tanks too.
 
Did not know the could have a wiper motor as I have never seen one with a cab and how else would they have a wiper motor?
 
save yourself the headache and just replace it with an electric one, best thing that ever happened to
wipers. drove enough trucks with air wipers too fast to slow or just wouldn't work.

Like I said in my OP, I don't plan to chase the problem too far in the air motor because an electric is half the price of an air unit.
