I have lost all faith in the garage I am going to. I had an alternator replaced and now my air conditioner isn't working, specifically it is blowing hot air. There is plenty of refrigerant in the system. Seems like the clutch is not engaging the compressor. It never turns on.
It worked fine when I brought it in. The garage is now telling me I need a new PCM because it is not sending a signal to the AC unit as well as a new AC clutch because every time it tries to engage the clutch, it blows a fuse. If the PCM is not sending a signal to the AC unit then how can the clutch blow the fuse?
Does this make sense to anyone?
Thanks!

Thanks for such a quick reply, I really appreciate it!
I am not familiar with the PCM. Is it possible that it is bad and can not send a signal to AC unit? Could there be some other components that come in to play here that could be preventing the PCM from sending the signal and turning on the AC unit?
Thanks again!

Anything is possible but it's highly unlikely and it would have nothing to do with a blown fuse if that were the case. Many techs blame the computer when they just can't figure out what the problem is. The computer ends up being replaced for nothing and you still have the problem.

Just that: How the heck did you ascertain that?

PCM won't cause a fuse to blow because it is on the ground side of the load. They need to recheck their work and make sure they didn't pinch any wires during their repair.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

I'm concluding that there was enough refrigerant in the system due to the fact that the AC was working and blowing extremely cold air when I brought the van in to get the alternator replaced.

Just as a follow up to my original post, I picked up the van and will be bringing it somewhere else. I was told that I need a new PCM, a new AC clutch and now something having to do with the transmission.
Since having the alternator replaced, I still do not have AC and now the vehicle is driving like it will stall at any moment. Also, the gear shift indicator is not lighting up the current gear but all the lights on the indicator are lit up.
Question: Should I find a garage that specializes in dealing with electronics? or should I just bring the vehicle to the dealer to get this mess sorted out? Any suggestions? Thanks!

You've concuded that on that!! Now you are trying to re-engineer the space shuttle and have not clue if there's even gas in it and the right amount. All bets off on all other testing until you DON'T GUESS BUT KNOW THAT OR ARE JUST SPINNING YOUR WHEELS. I a few seconds it could be empty just left and parked and you haven't ruled out 65% +/- of reasons A/C quits working!
This and many will default to not engaging clutch with wrong or inaccurate info that the system is low. Takes two seconds to at least know there's pressure and some gas in the system and you are going off on tangents without ruling out problem #1.
Do you even so much as have static pressure in line with the temperature at hand? If not stop there and fix that even if not the overall problem,
