Had problems with the dash air on our Winnebago 2011 Adventurer and had the compressor replaced because the seals were bad we were told. it was under warranty so no cost to us. However, the air still continued to blow warm air. Went back to Ford truck dealer and they found a hose had been rubbing against something under or on the chassis. This hose was not warranted so had to pay for repairs. That did, however, solve the problem and air is cold. The dealer told us that because the hose wasn't a ford installed part, they couldn't cover it. Has anyone else had this same problem with that or any hose rupture do to rubbing against the chassis?
