Fan runs all the time when furnace is on

The title says it all. I have a 2019 cougar 29BHL and it just started this... When the Furnace is on the AC fan runs on Low all the time.. It doesn't matter if it is on "fan Auto" or "fan Off" (of course it will the fan runs on Low and High). I did have it in this past fall for the problem with the furnace not turning on when the temp is below 40 and no, it was never fixed. I hate to take it in, I don't think they will fix it anyway and break other items while I have it there. I'll fix it myself with your help.
Thanks!

Maybe it's your thermostat. Is yours like the one pictured? Some have reported that these can be glitchy. You might pull the cover off and try it again to see if it works correctly. I have this same Tstat but so far it works fine. Perhaps others will have other insights

Sorry, I forgot to tell that I have the POS In-Command system. If I had the one you are showing I'd have it apart and tested by now.
Thanks for trying though.
