The Occasional Blowing Hot Air A/C Fix??

[Skipper]

Found this on another forum. It was on a 2006 model 29B. Not sure what the reversal of those hoses (water or vacuum???) are really doing to make the air colder. Would like to hear from y'all after review.

The post; "Fixed the problem with the AC blowing hot during high RPM's or climbing. There are two hoses that were install incorrectly and must be switched. Easy access from the doghouse. Four images are attached." Upper right corner of pic is the location of hoses. Enlarge pic for better view.

That situation when the engine is under load is fairly common, I suspect a loss of vacuum is causing the blend doors to change position. I didn't read the message but was a particular chassis and model year mentioned?

I had the same problem with my 1998 Adventurer, it turned out to be a vacuum leak... mechanic found the leak and problem solved.
