Air was blowing cold for 15 to 20 minutes and started blowing hot. Van sat in the driveway for several hours and when started back up A/C was blowing cold again for about 15 to 20 min and then hot. Compressor is ok, freon level is ok, relays in the fuse block are ok, but the compressor clutch will not engage.

I Had the same problem. I was told that I should evacuate and then refill the freon to clear any blockage. Did that - but did not work. Turned out it was the compressor clutch that was faulty. I purchased a re-manufactured compressor on e-bay (Cost about $200 plus shipping) It was the cheapest I found anywhere on the internet.

Hi there. When a compressor is replaced, two things are in fact being replaced - both the compressor and the refrigerant (Freon) and if the problem is resolved as a result which of those two replaced elements caused the original problem? Well you will never know and so before the compressor is replaced you need to have you’re A/C system recharged – it’s by far the most cost effective initial thing to do. In general A/C systems loose at least 10% of their effectiveness each year through loss of refrigerant and so given the age of your car; it’s the first thing to focus on. A professional A/C centre will also be able to tell you whether your compressor is working properly after having a refrigerant recharge by the monitoring the operating pressures in the A/C system.

If it is engageing rapidly it means it needs to be charged.

If Freon was "added", the system may have moisture in it and that causes blockage of the expansion valveand makes the soamolies hijack oil tankers. Just kidding. Figured this would be all foreign to you anyway, no offence.
Ok, Adding freon is not really a good fix. The system should be evacuated with a vacuum pump to remove any moisture in the system which will freeze and block the expansion valve, Hence, no cooling.Having the signs of this problem already should have called for evacuation. Adding freon from a kit increases the possibility of introducing more moisture into the system. You will need to have it properly service at this point. The drier will also let go of any moistue it has trapped when evacuated for 30 minutes @ 29 in. of vacuum - good luck
