my 2002 has an amazing dash air. i did have to change the compressor when i got the coach 5 years ago or so, but it worked great when charged. but it would lose charge in a week or so. so after several years of just putting freon in it when i needed it to work, i went to task to find the leak. of course with richards assistance. air conditioning just doesnt compute with me, but i am learning.
a year ago i traced the leak to the high pressure side hose fitting on the compressor. i found a small shop about an hour from my house in an industrial strip mall that makes custom hoses. i took the coach there, barely fitting in the small paths around the building. he cut the old fitting off, remanned the one going into the compressor, crimped a new hose on, put 2 new dryers on, new caps and all for like 60 bucks or something like that.
i went home, evacuated it, charged it up and things were good. it has been about 9 months since i did that and since we are headed out soon, forest and i checked it out today. of course i couldnt remember the readings i was supposed to get so dr richard was consulted.
he reminded me to use the pressure/temp charts for an rv with longggg hoses, not an automotive chart.
on startup today it blew cold, and the with 80 degree ambient i was at about 12psi low and 160 on the high side.
so i put a few ounces of freon in it and it was at 16-18 low and 180 high. blowing about 30 degree air at dash.
so, the hose fix worked and was cheap
and maybe i will remember the charge readings this time....or not
