Why is my A/C button/light blinking??
I've always turrned on my a/c in the winter time every other week to circulate the system so seals and o-rings won't dry out, causing leaks.. Tonite I turned on the a/c and the yellow light on the button started blinking and shut off after 4 seconds.. Its 32 degrees out here.. Does that have something to do with this? 2002 z06.. Never had a problem on any other car i have owned.. Thanks for the help

A/C does not operate below 35*, if it did your compressor would be short-lived.
People in northern states often go 6+ months w/o it, and don't experience any seal problems.

All you have to do is start the car, warm it up, turn on your front defrosters and the a/c compressor will automatically run. It's part of the defrost system.

Its working normally. At 32 degrees the ac is inhibited and the light flashes to let you know.I guess its rare to get 32 degrees in TX

Although I store my car in the winter, I like to start it 2-3 times during the season, just to circulate the fluids, and keep the valve springs from sitting too long in one position. I also run the defroster, so the a/c compressor circulates the oil througn the system.

Thanks for all the good info. I should have looked at my owners manual first..
i kind of figured it was a normal thing in cold temps.. I just wanted more/correct info... And yes.. It does not get this cold very often in Dallas Tx,, The CAI is working really well in these cold temps

Ok... so it's a normal thing ofr the heater to turn onthe AC with the defroster set?
I have tried to turn mine OFF ( AC button ) and it blinks and then stays on.
Thought there was something wrong.

BINGO!!

If you don't drive it you shouldn't do this. It is very bad for the car. Idling does nothing but build moisture and acids inside the engine and exhaust and it doesn't get hot enough to cook it out. If you are going to start it take it out for a 30 mile drive there are plenty of winter days to do that. I just drove mine last week and will probably drive it again in January when I get back from rainy and cold Southern California.

Read post #6 again. Even if people don't use their a/c for 6mos +, if they turn on the front defroster at anytime during that period, they are maintaining their seals.

Bill, I appreciate your input, however there are generally not enough days here where the roads are BOTH dry and road salt free. (Plus, I take the liability and collision insurance off my cars for the winter) This practice is something I've done with a number of cars over the last 34 years, and so far, there have been no repercussions. As I mentioned, I personally do not like the engine sitting in a static position for 4 months....
