Dash heater /defroster not working

[tjdehall1]

Hello, we bought a used 2018 Thor Hurricane 29m and just found we have no heat coming to the dash for the defroster. Any suggestions?

The "dryer hose" under the dash probably has come loose somewhere.

Thank you, we will check for that.

When you have it on defroster can you 'hear' the air movement? It may be that simple as a hose has come undone. It could be rodent damage. It could be a failed blend door. Take off the cover in front of the steering wheel and follow the hoses for a start.

2nd what Lt Keefer said. While on a recent trip, our dash fan would squeal on any speed except high. Found a replacement motor at NA PA and did the swap on a day we weren't traveling. Cost was just over $50.

Hope your problem is a loose hose. Much easier fix!

Thank you. We can hear and feel cold air coming from vents but no warm or hot air will come out.
