AC issue
The AC on my 2006 is cutting out at random times. Blower is still going but no cold air. If I turn the system off for a minute or two and then back on it starts working again. 106 degrees in Texas I would really like to have my AC.
Any ideas?

Was on issue early on...over charging (by .5 psi) of AC system from the factory. Easy fix...just take to dealer to discharge and probably they will replace over pressure sensor.

Don't think it's an over pressure issue. The car is over 3 years old and the problem just popped up. I'm guessing it's low on freon

Your HVAc has a high and low pressure switch that disengages your compressor when either state is sensed. Take your car to a professional or your trusted car mechanic and have them service the AC system

Probably low freon...automotive A/C systems need to be used, or the seals can dry out and leak...its best to run the A/C once a month for a few minutes..even in the winter, to keep the oil stirred up.You can buy a kit for about $25 and easily check the pressure yourself...then freon is only about $7 a can...very simple...

Freon is a DuPont trademark that is used by those of us who are uneducated ***** to refer loosely to fluorocarbon refrigerants in general...R-11, R-12, R-22, R134a etc. 134a is not bad for the ozone layer but is still a "greenhouse gas" and is already under fire for that....California is considering limiting its use....they won't be happy until we have no air conditioning at all...

25-45 psi on the low side of the system while it is running. All the kits have good instructions and are easy to use.
The Corvette system is just a standard A/C system like any other GM car...nothing unusual.

Mine did only when 120 or higher outside. My local A/C guy hit the schrader valve and let out 2 ppfffttts of 'freon', and this fixed it.
And this is what I would do if I had no warranty. I had a warranty and eventually had the dealer check it and do it by the book.

If it only happened or started to happen on the hottest and most humid days, it could be overcharged. That's what we found with some early '05's.

With low freon, you will see the gauge go down gradually when the compressor engages, but it will be pulled down TOO low and the switch will then disengage the comp. Press will come up and then it will engage again, and the cycle repeats. With enough freon in it, the compressor will pull the pressure down, but only to a point, and then it will not dip lower and kick in the switch that disengages the compressor. Equilibrium! This is why the amount of freon is important. Too much and the compressor can't pull the pressure down enough, too little and the compressor pulls it down too much. There are high and low pressure switches that disengage the compressor...the correct pressure is when it stays between the two. With a $20 kit from WalMart or an auto parts store, this changing of the pressure is very obvious. But unlike most things on this forum, more isn't necessarily better...add enough freon to stop the 'pull down' and thats perfect...more won't make things cooler. If there is too much and the compressor is disengaged more often, it will make things warmer.

The only way to know if you have the proper charge is to evacuate the system and recharge with refrigerant by weight only. In a car pressures change by RPM and air flow. I would think you need someone that does this for a living to check it properly.
