I need to work on my heather, which is why I took out my Kuhlmeister airconditioner. It always worked fine. That is to say, it blows out air and all the switches are working. It needs the proper gas for the air to produce cool air. I will not re-install it, as I do not really need an airconditioner where I drive my Pagoda. If you are interested, send me a reply and we will talk further. I can ship it to wherever you are.
