1997 Quest A/C Problem

Help Friends! The A/C in my Quest is not working. Everything works but when I press the A/C button it doen not blow cold AIR. To the hearing of my ear I dont hear the change kicking in .... and most of all I dont have COLD A/C quality air. The GREEN LIGHT on the A/C button lights up normally. The blowers work....I checked the the A/C charge and its fully charged ....I used a gauge I bought to measure it. So refrigerant doesn't seem to be the problem. I recently filled it with Refrigerant R-134a. WHAT COULD IT BE??? HELP PLEASE????

Mercury villager forums has a thread.

how do i close my window in the rear side? you may need a compressor it has to kick in to blow the air, get one from the junk yard. i just got my AC serviced today with 134A
