Dash AC Problem
My dash AC stays on regardless of the switch setting. The compressor appears to stay engaged all the time. It's a 2006 HR with Workhorse 8.1. Where do I Start??? Thanks for any help.

Doggone! Relay was supposed to solve ALL the problems! You can see from the few pins it has and the diagram on it, that all it's able to do is be ON or OFF when told to. Other odd behavior is coming from somewhere else.
Couple more questions:
Did the Compressor run in all selections before?
Are your A/C controls Manual or Electronic?
Does that Manual linked in this thread match your Coach?
Did the sound of the compressor change from before changing the relay to after changing it?
Do you know if your system is meant to cycle? Many modern ones do not.
Answers:
Yes, ran in all selections, including "off"
AC controls are manual (knob selector)
The manual in the link is correct
Yes, the compressor never made the puffing sound before.
Not sure if it should cycle; just assumed it should
