Me and My Bro. had a 1994 5.0 then sold it back in 1998.
It bacame a Fix Or Repair Daily issue with the A/C
until we fixed the entire A/C system.
You need a new compressor and you also have a leak somewhere. I am almost 100% sure of that.

As long as you can rotate the clutch on the A/C by hand, you won't need a new compressor.
The most common repairs on these cars for the A/C are a failed pressure switch (mounted into the Accumulator at the back passengers corner of the engine bay) or a leaking green o-ring.
I'd check the system for pressure first and if the pressure is low, recharge with some R134a. If the system does not work again after a day or two, you have a leak. Replace all of the o-rings in the system since they're old anyway. Draw a vacuum and see if the system will hold the vacuum. If it will, recharge again with R134a and add some of the colored PAG46 oil so that you can see if a leak makes itself apparent again.

If you turned the AC knob and NOTHING came out, you need to look into a blower motor issue. But that would be a different issue than blowing hot air.

also when you recharge your system , pull the plug of the pressure switch and use a jumper wire in the plug. If your A/C system is completely empty of freon you will have to pull a vacuum on the system before you recharge it....( after you locate and repair the leak)
