hey guys.
I got Cherokee 93 last week.
but I don't know why heating/A.C doesn't blowing.
I tried to find the reason, so someone recommended fill coolant
Yesterday, I filled the coolant, but it still doesn't work.

Anyone can help me? plz.

is it blowing out the top vent - if so and nothing else check your vacuum. Under the front left bumper. check hoses etc too

ok so I have a 93 cherokee too and mine was doing the same thing... It turned out the my blower motor wasnt getting any power. I hooked the blower up to a power source and it turned right on but when I disconnected it the blower stopped working. This was my case. Yours could be either the blower being completly out or the wireing is bad like mine. I dont know could be something else..thats just my guess

I have never dealt with this in the Cherokee before, but everything else I've worked on the blower motor has had a relay. The fact that you can supply direct power and make it functional tells me you can rule out the blower motor. Relay or wiring has to be your problem. 9 out of 10 times when I assume wiring, I'm wrong, start with relays and fuses and rule that out before chasing wires (unless you did something lately to bash up the Jeep where it might have damaged wires). Hope this helps.
