Toyota Repair: sienna a/c, blow cold, c tech

Question
my van's a/c doesn't blow cold. it stopped blowing cold air all of a sudden.

Answer
I can't help with that because there are too may things that can cause the a/c to stop working, the most common cause is that there is a leak and the freon has leaked out, the best way to go about this is to have a qualified a/c tech check the system.
