A/C drain tube not draining

Yahoo Message Number: 17113
Our middle A/C unit doesn't seem to be draining properly. It's leaking over the side of the coach. So far there is no water in the coach. I pulled the top cover and the inside cover of the A/C but its not obvious to me how to fix the problem. The A/C units are Coleman Mach Heat Pumps. The front and rear units are working fine. There is some moisture coming from the middle drain tube but most seems to be coming out of the side of the condenser housing. Any suggestions?

Not sure how yours is set up, but on my 03 Allure, one solution is to keep the front-end of the coach higher than the rear. Just a little will usually work to allow the water to drain out the rear drain tube.
On mine, all the water drains torward the rear. I let the coach level with the automatic HWH system, then when it's done, put the HWH on manual, then raise the front or lower the rear a bit. I have a small bubble level I place on the floor next to the HWH controls. This is probably not the manufacture's intended method to use, but it usually works. I'm still trouble shooting and brainstorming a better method.
As a precaution, we place towels underneath just in case. If you find a better way, please let us know. Thanks

Thanks for the suggestion but we have three AC and they all have their own relief tube. All exit the driver side of the coach and two out of three are working fine. The middle was working fine until about two days ago. I suspect its clogged but I don't know for sure how to reach the clog.

Bob, I suggest that you take your compressed air hose and mate it up with the ground end of the A/C drain tube and blow it out from the bottom. This has worked for me in the past.
