Hi ! Welcome to IRV2! We're sure glad you joined the gang!
Noticed that you are kinda new on IRV2 and wanted to say hello! If you will post the year and model number of your rig it will be easier to get help. Have fun and keep her between the ditches!
Good luck, happy trails, and God bless!

If it’s a new to you DP, the coolant loop may be closed. Some people, ( me included) close their heater loop to aid summer ac cooling.

We're having the same issue. The mechanic that looked at it could not figure it out. Using the Aqua Hot to stay warm for now.

I have the same issue. Here are the steps I’ve taken so far. I confirmed that 12v is delivered and changes to the valve that open/closes the loop from the radiator. I disconnected the loop from the supply side of the valve and confirmed coolant flow. I check operation of various vacuum valves under dash that control airflow . What’s next for me is to remove the outlet side of the valve to confirm flow when open and then to test heater core for blockage. I am betting it’s a blocked heater core as my MH was owned by a couple in Florida and they seldom used the heater.

Most likely is the valve that allows hot water into the heater coil either is bad or does not have electricity to it. Fuse or heater switch could be the culprit. If you are getting cold air then fan and fan switch is good.

+1 That valve is the likely culprit they have a been known to fail
