    At this point. All you can do is assume everything works fine and start repairs.

    Would have been nice to know what the pressures were. But most people don't have a clue as to how to accurately and professionally charge or read the ac.

    I feel sorry for you all. It's a crapshoot out there.

    The fan at idle doesn't kick on untill high pressure reaches a certain point. Thus, the high pressure switch i mentioned earlier.

    It works with the ac in the same manner as the radiator. Provided everything else in the system works

    Hmm I replaced the sensor this afternoon and drove it fixed my engine fan staying on all the time. I had hardly any cool air while driving. It wouldn't even cool the inside to 74 while driving and it was barley 83 outside.

    I'd hate to just start throwing new parts at this because it's gonna get pricey very fast. Heck the transducer alone was $101. Plus the $150 for loves to charge the system

    You won't have any air cool. All the freon got lost in your earlier posts.

    I'd probably try to find a shop more knowledgeable then loves. That can get you in quickly if you're out on the road.

    You don't need a semi shop. Any shop with an hvac machine will work. I'm guessing you still got the label underhood that says amount system holds?

    The hose didn't break till I left the shop. 10 mins after I parked and high idled the hose broke. Something else is going on just don't know what.

    Overcharged, blockage, worn out hose, OR, it was rubbing against something and rubbed a hole.

    I had a brand new aftermarket hose do that. It was rubbing against the valve cover. The motor moved slightly enough to rub a hole.

    I don't know what area you're looking at.

    It don't take long for that high pressure quick connect to get very hot.

    I top off a lot of cars. Usually only takes about 2 oz. That high pressure connector goes from warm to hot really quickly.

    I buy my refrigerant in 30 lb. Cylinders.
    You gotta be licensed to buy more then 2 lbs.
