Can be a thermostat stuck open. Replace the thermostat and service the cooling system. Can also be a heater control valve malfunction.

Either you need to pen your vents or there is some vent obstruction.
There is a dead short to ground in the circuit.
This is the classic symptom for blend door failure on the Grand Cherokee. Check heatertreater.net for diagnostic information and an inexpensive fix.

the horn itself may be screwed on too tight. Remove the horn cover, usually by prying it off, and there will be three Phillips head screws. Loosen those screws a little and that should solve it.

One of the reasons a 2000 Jeep Cherokee heater would randomly blow cold air and then hot air and then cold might be that there is a problem with the hot/cold duct. The air or a vent might be inadvertently blowing periodically.
Sounds like there is an overload in a wire and it is blowing the fuses to keep from doing more serious damage. Have the wires to that fuse traced and tested to see if the wire is bad or if the ground wire is loose.
You may have a faulty expansion valve. It may prevent compressor from running long enough to cool your car.
