Cruise Air

Hi all, I had turned on the rear cruise air while in Lake Havasu april 1-4. The air conditioner just cycled never did get cool. We came back home thinking we will need to get it charged sometime. Well, what it was, was the motor bearings had gotton a little rusty and the motor wouldn't start up, it was just trying to and would try and stop. You can't hear the air conditioner since the fans are running on the inside of the coach. Some motors have to be oiled, didn't know that, now I do. So this should get put on your to do list, check first to see if you have the oil type, one of my three is the oil type, the bedroom. maybe no one has this type of air. Put five drops in both inlets annually. Run the unit at least four time a year to keep the bearings lubed.

Question... do all cruise air's have the ability to heat also? my 96 marathon friend said his does. Mine are from the 1986 era.

No, My 1991 Liberty does not have the heat cycle. It is my belief you would have to install new units in the belly to gain the heat pump feature. Ken

You would also have to install the SMX control. It is likely you have the old controls with the three black knobs.

Thanks guys, thought if I had it and didn't know it after owning it for 8 years that would be bad, very bad.
