AC light flickers. Heater goes on. Panel?

First:
Merry Christmas and may this New Year bring us all Health, Peace and Love..

Today my wife started to pack as we leave Sunday for a week! Yeahhh....
She found the heater blowing hot inside RV......

I think my dual AC climate control panel is messed up.
It's had some wear in the past in the 2 toggles that you click up and down to select cool or low or high or auto. Whenever we put it back to off the green light sometimes flickers.

Today I found my heater on and the propane tank was down almost 50%. God know how long the heater has been on?
It hasn't been cold and we don't have it set up for auto heater.

I think I got lucky because it could of been worst.


So should I just replace the control panel?
Who sells these? Many one had this happen to them?

In the meantime, I opened the outside panel for the heater and turned off the heater switch...
That way my propane won get consumed and the heater won't come on, beside I need my LP for the fridge while on the road...

Thks!
