okay - so NOW what? UPDATE !!!!!!!!
81 Corvette-
everything in my AC system has been replaced except the condensor.
took it to the shop to get it flushed , pull a vacuum and fill.
So thats what they do.
Everyhting seems to be operating correctly, AC compreesor is cycling...
pressure readings are correct...
however there is NO cold air coming out of the vents.
Any one have any ideas , so I can get my car back and actually drive it for once in the past 2 months?
heres my previous post on the topic. http://forums.corvetteforum.com/zerothread?id=361133
thanks

also - the door is opening and closing in the heater box....
I can flip the temp lever and get blazing heat out of the vents and I can turn it to cold and the temp out of the vents gets much cooler...
but its not AC cool.....its just warm air.

Re: okay - so NOW what? (ksems)
got the car back today....
the AC is working
It certainly isnt ice cold coming out of the vents, but it is cool air.
Im not sure these cars ever had "ice-cold" air.
The mechanic put a variably orifice filter in it to make it run a little cooler...he also adjusted the heater door ( said it wasnt closing all the way )
I may eventually take it to an AC Specialist , but not right now.
I need some driving time.
I had the lower control arm bushings and lower ball joints replaced as well......front end is definitely tighter now

I agree. Wish I could help but I don't know about ACs.
Damn, what luck. Don't sell it, just keep at it. You'll figure it out sooner
or later. 81s are a nice year model.
:mad :confused: :smash: :seeya

Who's servicing your AC . . . Bubba? :smash: These units are not rocket science -- they're plain ol' GM stuff!
Go find a REAL A/C shop. It may not be cheap, but it'll get fixed right the first time. Although I spent close to a thousand bucks, I feel it was worth every penny not to be fussing with the AC. And the shop discovered the fan clutch was NFG, too. So now I have COLD air and an engine that doesn't overheat (well not too much). Worth the investment in my opinion.

Re: okay - so NOW what? UPDATE !!!!!!!! (page62)
well -
I have since learned that the pressure readings are the same on BOTH high and low lines....somewhere around 120....and my blower stopped working while I was standing there and they were checking wiring.......
this sucks :mad:

Re: okay - so NOW what? UPDATE !!!!!!!! (ksems)
car is back once more from the shop....
AC is working consistently now.....
however the AC Compressor is cyling alot....sometimes every 2 seconds ....
while driving it makes you feel like someone else is constantly tapping the gas and then releasing...its cyling to much - correct?
I thought maybe it was the pressure switch , so I put a new one on...
The mechanic said that the new 134a is a different pressure than the old r-012 so it will cause the compressor to cycle differently.
I changed the switch but it had no affect. :(
any ideas why it is cycling so much????
thanks

Re: okay - so NOW what? UPDATE !!!!!!!! (ksems)
The compressor, when fully charged, should not cycle at idle on a medium hot day. Low side pressure should be in the 40-45 range. As you bring the rpms up to about 1500 the low side pressure will drop to ~20 with a non-adjustable stock clutch cycling switch. If you have an adjustable switch, the pressure may drop into the teens before the comp kicks off. If you are cycling at idle you are most likely undercharged. You either need to buy the required tools (gauges,hoses, et al) and fix it yourself or find a competent A/C shop.

Re: okay - so NOW what? UPDATE !!!!!!!! (FeedVaal)
I spent close to a thousand bucks, but my AC is flawless and amazingly cold, even in the 100 degree heat we're having right now.If only I could get the engine to run a few degrees cooler... :nonod:
