Looks great. Removing the carpet in my stairwell is in my near future. My wife suggested diamond plate to replace it. Haven't decided yet, but I'm not against it. Where did you source your stair tread?

Good idea Rodger. I'm taking it for a drive tomorrow and will clamp off one of the hoses and see what happens. I'm glad that at least the system is producing cold. I just have to figure out how to get it out. Thank You. From what I have been able to gather, it sounds like on a lot of coaches the air is blown past the heater core and evaporator simultaneously so the water valve does all the work of metering the temperature. I will find out tomorrow if it's the culprit when I clamp one of the hoses off.

I recently purchase a 2002 Dynasty. It was pretty cold out when I tested it and it seemed like it was working. On the way home from purchasing I realized it is blowing only hot air. So far I have figured out the compressor is doing its job and it is good and cold on one side of the evaporator. I can hear what sounds like a door opening or closing by air action in any of the mode positions for where the heat/air is pushed i.e. defrost, vents, floor, etc. There are no similar noises when switching to ac mode. I am inclined to believe the issue is with the water valve on the firewall behind the generator. Is there a way to check voltage at the valve connector that will tell me the valve is getting the proper open or close signal? They are pretty small pins so will have to figure out how to get a meter lead on them. I want to avoid getting inside the dash if I can. Also if I find it is the hot water valve, am I likely to dump a bunch of coolant or just the contents of the heater core when I change it. Last question, is there a separate fuse for the heater control different than that of the blower which works fine. Thanks in advance. If I'm way off base in my troubleshooting, please straighten me out.
