The freon is in red? That's bad if too much is in the lines it can't expand properly so it will blow hot. In the rear by the tail lights should see a vent it is behind that rear panel
Check fueses and relays in fuse box.Look for blown fuse for compressor. Do not over fill with freon it will lock up compressor and don't forget the oil for compressor.if it's in red let some out in your recovery tank.if you have one wink.wink. the relays are big and grey you can switch with one of the others with
Check fuses and relays in fuse box

Ok so the AC clutch fuse keep blowing. And I let some of it out into the recovery tank but it was just air. Probably from being old and sitting in a lot. Wink. So I recharged it. And right in the middle of doing so the darn fuse blew again! Arrrgh lol now what?

SOURCE: Rear air conditioning setting
It sounds like your rear temp. blend door is malfunctioning. You might could get a known good controller from (ebay,junkyard,craigslist) then plug it in. If this does not fix, it is probably a blend door actuator issue.
SOURCE: air and heat not blowing air through vents
Either Your fan switch is burned out or you blower motor is no good, your blower motor is on the passenger side under the dash. Before you replace any parts you need to check your fuses and relays under your hood and in the car. Usually if your fan switch goes bad you will still get some air blowing thru the vents, so my guess would be blower motor, If its not a blown fuse or relay.
SOURCE: ac vent problem
Damper/flap for driver's side is probably stuck. Try moving the selector from cold to hot several times. Also, move the recirc/outside air control if the previous doesn't work.
SOURCE: ac blowing hot air
the blend door actuator located on the air box (right hand side under dash) is prob. inop. worst case senerio the blend door its self is broken. I have replaced the actuator more than anything.
SOURCE: raer a/c works but front blows hot air on my 99 tahoe
My 04 tahoe had to have the a/c door actuator replaced as well, same problem. 100.00 part from dealer if you want to do it yourself.
