its a 95 v6 runner... a/c works whenever it wants too... when you start the car cold the a/c works fine i mean ice cold..  after a while the a/c is dead then you'll start to smell something sour...and warm air start to flow through...there is no leak cause it works everytime the truck is start up cold and the only time is when the car is warm..

Check and make sure the AC clutch stays engaged  when it starts to blow hot.

is your electric fan working?  sound like your ac got hot and built too much pressure  and the high lo switch cut off the ac .    or go get cheap ac guage from auto part store  to see where your pressure at

a/c clutch is engaged when it blow hot air...but what i notice is that when the a/c work the rpm drop and when it starts to blow hot air the rpm jumps.
