So on my pontiac montana, the a/c works in the front but blows hot air in the back vents. Sometimes it will work but Most of the time it blows hot air in the back even when it is cool outside. I have tried to put Freon in it and that doesn't seem to work. What can I do to fix it on my end. Or what can it be Thanks!?
