Hi everyone,
The A/C in my 2006 G35 sedan has stopped blowing cold air. I can even crank it down to 60 degrees, and it will still blow warm air. I can raise the temperature just fine, and it will blow hot air, but when I want cold air, all I get is just warm air. I do know that I need to replace my serpentine belts, and I know those have to do with A/C but I doubt that is the problem. Does anyone know what the problem could be?

Thanks!

 

the first thing to do is check and see if there are any leaks from the A/C hoses (specially the low pressure hose) if there is dirty (not dust) build up on the hose most likely there is a leak. When there is not enough freon in the system the compressor won't turn on.
