Can the Air Conditioner Refrigerant Dry Up?

[gatorglaze]

Okay so im trying to find out exactly why my AC doesnt work. However this may possibly be the first time i tried using my AC for a long time in about 7 months because 99.9% of the time, i roll down windows but recently i tried using it and it blew out warm air. So my question is, can the refrigerant dry up after long *** periods of no use? And our cars use R134a right? Not freon anymore?

Dumb question, but I have to ask (b/c it happened to me when I first bought my car ): Is the AC button pressed?

[gatorglaze]

Yes, its pressed and i've tried max AC as well. It's the same temperature air that blows out when the AC light is off.

Ah man, that sucks. I see a trip to the dealership in your near future...

well im not to sure about the drying up part but I do remember that the compressor gets messed up if you dont use it for a LONG time.

Well, being EPA Certified I can help you with your freon concerns. First, R134a is still freon, its just a more eco-friendly version that doesn't burn holes in the o-zone like older R114 does. Freon doesn't "dry up". However, it can be contaminated by oxygen or water in the freon lines. Also it can leak out if a seal in the system isn't installed correctly. Your main hub to the air conditioning system is going to be the compressor. However there is no sure fire way to check it on your own, short of pressing the AC button inside the car. A lot of times with AC systems, after you turn them on for the first time in a while, the freon will take a while to circulate and start working properly. Start your car outside, and let the motor run for a good 10-15 min with the AC on. This might be your problem. Autozone, and places like that, have AC test stations and such. If you don't want to go by Nissan, then take it to them. Since the car is still under warranty though, just take it to Nissan and have them repair the problem. Hope this helps
