Unhappy Dash Heater/AC

Our AC cooling has quit. Looking for the hot water control on/off valve. I have a National Tradewind 2001 motor home.

had the same problem with my 89 HR. Open the hood and look for the wire that connects from the dash to the valve. Mine was ceased up. You can still turn the valve by hand. Mine is located on the upper left hand side, just above the rad.
hope this helps. I almost froze my buns coming home from SC last Nov.

Dash Heater/AC

Thanks for the information. Still looking for parts. Any answers for older motor homes?

You may not have a hot coolant valve on your DP.

Ours did, but it was mounted just forward of and below the engine in the engine compartment. I had it removed 10 years ago.

I assume you have already eliminated the electrical causes of no AC such as fuses, relays, and compressor clutch.
