Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

If you can tell me which chassis your Jayco is built on I will see if I can find you a diagram , this type of problem is usually caused by a loss of vacuum or a failing control panel. Post back on whether you have a GM ,Ford or Dodge power plant and I have a look and see if we can find the information you need,

ford e-450
Expert:  Ron replied 4 months ago.

The common source for a vacuum leak on the E 450 is usually the vacuum storage reservoir but to be sure you are going to need to do some testing. I have enclosed the complete AC diag file in the link below. You are going to want to start your testing at pinpoint test A1. Have a look and post back if you have more questions and or need more help.
