[DMCForum] Re: A/C performance

Since I bought the car it hasnt been able to keep me from sweating. 
It seems to blow out hard but doesnt seem cold enough to make a real 
difference.  It is cool near the vents, but not cold when on full 
blast.  I know some air is leaking out in the door jamb but it isnt 
a problem of speed, I want ice cold air coming out.  If I need more 
freon, the air temperature would be warm right away or gradually get 
warmer?  I am sure my fans are working fine.
