AC in my 1992 Ford Explorer blows out warm air. Any ideas on why this is happening?

Question

I have a 1992 ford explorer, the ac used to work perfect up until a few months ago. So I recently had it recharged, it worked for about an hour then started blowing out hot air again. Now I have had it recharged, the pump replaced, and have had a mechanic look for leaks which none were found. Does anyone out there have any idea what the problem could be??
Thank you so much!

Answer 1

could be a couple of things. first the blend air door, thats the door that controls the hot and cold. it could be stuck in the hot position.
second, the system has a orfice tube, it could be blowed open, not to likely but it can happen
third, is the compressor even turning on
fourth, is it still full of freon, those fords are known for there leaks
fifth, get a different mechanic

Answer 2

I have the same problem with a car 1 year younger than yours. My mechanic told me I need to replace the AC system completely, and that costs 500 freaking dollars. I'm not paying that much, but if you want to, go ahead, It's not very hot right now where I live, so I just keep my windows down

Sounds like it could be your blend door is sticking or not staying open which is a problem in my Expedition. It is costly to fix too, I usually just keep turning it back and forth between vent and air conditioning and turn it off and on until it stays on air conditioning.
