Hello to all ! Sorry for being absent from this forum for awhile. Since this old-timer got an IPhone, I haven't used my computer that much anymore. Anyway.... the dash ac is not working anymore. Since it has a Mercedes engine, we contacted our local Mercedes dealer and told them about the dash ac not working. Got no help from them. Winnebago put a 2009 Mercedes engine in our 2010 motorhome and they told us that they couldn't help us, because they have no wiring diagram for a 2009 engine. So we took the Reyo to the local Dodge/Sprinter dealer. The system had no Freon in it at all. So they put Freon in and dye and told us to run the engine daily for 10 minutes with the ac on. Obviously there is a leak in the system. Now my husband and I worry that they won't find the leak and start replacing parts etc. and running up a huge bill. I am saying that, because we experienced the same thing when we had a Winnebago Journey back in 2000. Took it in for dash ac repair 6 times and they replaced everything under the sun. Thank God it was still under warranty! We finally contacted Winnebago and since we were vacationing in Florida, they hooked us up with an ac repair shop in Orlando, FL. And they finally fixed it. Had no more problems with it. So does anyone in this forum have any opinion on this or has any suggestions about what we can do? Thanks soo much!
