MY 4 RUNNER MAKES AN OCCASIONIAL PSTING SOUND LIKE AIR HISSING WHILE I HAVE THE AC RUNNING, THE AC IS BLOWING COLD & WORKING WELL. THE VO-TEC AUTO GUY DID NOT FIND A PROBLEM, BUT THE CAR DID NOT PST WHILE IT WAS THERE. ANY INFO WOULD HELP.

I am going out on a limb a little bit here and ask if there is a cabin filter that might require replacement.
