Yes, we have heat blowing from the couch fan:-) The original problem we had was the blower under the couch was not working in the Hi-Low or Tstat mode. Found the blower motor very stiff when I tried to rotate it by hand. So removed and replace the blower motor (Auto Zone P/N PM393 lifetime guarantee...credit to the gurus for finding P/N). So now it works on the Hi-Lo switch and noticed the toe kick fan running constantly with no way of controlling it....I could shut it off by pulling the ground off of the top small black cube relay at the Aqua Hot. Richard spent the day looking at his coach's black relays to figure out what they do. Some troubleshooting and correcting my SIPs ("self induced problems") i.e. wires swapped on the wrong terminals we have heat! The toe kick fan and front blower come on together.

The top clear relay goes to the forward AH zone pump for the front of the coach....the middle clear relay goes to the middle zone pump and heats the water bay zone....the bottom clear relay goes to the bedroom zone pump in the aft position....possibly the bathrooms not completely sure on that one. I would agree with Steve Bare your probably looking at the front blower motor having an issue.

Wanted to add; Someone, doing previous trouble shooting of the blower motor, had swapped the small black cube relays at the Aqua Hot. One of them may have been stuck closed. My jostling them around opened it up as they checked good when I put the meter to them. They are working as they should now!
