My air con isn't blowing cold. I'm going to recharge it.

I have a 1992 300, thus I am wondering if it is R134-A from the factory? If not, my car was obviously converted.

if u have R134a that meants its converted.

If you have R12 then its not converted

So I know if your compressor is shot, the AC light should blink.

Mine doesn't blink.

The pully spins, but I'm not sure the clutch is spinning too.

Clutch? Compressor? Simple recharge? Maybe tighten belt?

Is your AC bad? Please be more specific.

Le sigh.

I'm not sure. It blows hot.

Right now, the outside temp is over 90 degrees. (F)

It doesn't appear to idle up when the AC is turned on. The owner said it blew cool...but it obviously doesn't.

I know a belt is reasonably loose, so perhaps that is why.

Scenario:

AC on full blast on COLD. Blows hot.

Doesn't seem to idle up when AC engages. Clutch also does not appear to move with pulley.

AC light works and stays solid when engaged, but does not flash indicating a problem.

Why are you making multiple threads about you're broken AC? If the belt is loose get it tightened. I remember when my AC clutch went out it locked up, and if i tried to run the AC, the belt would start smoking because it couldn't turn the clutch. If your'es is spinning you might just be low on refrigerant. Get it filled up and test it for leaks. Good luck and stop making new threads with the same problem.

some ac systems will not turn the clutch on if its low on refrigerant

You guys are rediculous. Learn some patience with members.

all properly functioning (not necessarily cold, but functioning) a/c systems will not turn the clutch on unless a specified amount of refrigerant is in the system...

to the OP:

you need to do a couple things...

1) get the system level tested and find out whats in it - 134 or 12...

hopefully if its been converted, it was done correctly and all the r-12 was removed... if not, you might have problems finding someone to work on the system as it would then be considered "contaminated" and any a/c equipment hooked up to it would then be contaminated...

2a) system is charged, compressor doesn't work - pressure switch or control unit problem

2b) system isn't charged - have it charged, add a/c dye, look for leaks... have leaks fixed, recharge system, good to go...

the a/c is easy to see if the clutch is engaging - simply look at the center part of the compressor pulley - if its stopped, clutch is freewheeling, if it spings, clutch is engaged...

and one other thing... if you don't know what you are doing, please don't attempt a/c work yourself - you will harm the atmosphere, and more directly related, you could kill a properly working compressor...
