Question about Jeep Wrangler
There are two issues here.
If there is no heat or not hot enough, replace the thermostat and Check the coolant level.
No Air coming out could be either the Blower Motor, The Blower Motor Resistor pack or the switch in the dash. These jeeps are know to burn up the switch and wiring harness when the motor draws too many amps. I just installed all of the above in my 2000 4.0 Sport.

I would try to replace the blower motor resistor first,If that doesnt repair your problem you may wanna try replacing the blower speed switch.The resistor is located under the passenger side of the dash mounted in the heater box.

I'd replace blower resistor, usually found under hood on firewall on passenger side, or on duct work, inside under dash on passenger side,close to blower motor.

Defrost is the default. Pull the heater control panel off and make sure the vacuum lines are connected to the control. My Jeep had the same problem cause I was messing with the radio. Hope this helps.

Check water pump and make sure that its working. Should be circulating antifreeze in radiator and in engine. You can also check and the head gasket and make sure its NOT blown. Good luck and thanks for using FIX YA
