air dryer on coach is stuck open and I can't build up any air.

Dads Mechanic :

Sorry for your trouble. have you checked the governor on the compressor, I havee found this to be the usual problem in this area. Thanks for coming to Just Answers. Jim!!!

Customer: How do you check the compressor governor ?
Dads Mechanic :

sometime if you disconnect the small line that goes to the purge valve on the air dryier it will start to pump air. Sometimes if you just tap on the governor it will reset. Jim!!!
