No heat just cold air


Is the gauge showing the engine is warming up to normal temp ?
Are the heater hoses getting hot ?
If the heater core is getting hot, it could be a blend door problem. The blend doors direct air thru the heater core and the ac evaporator among other things.

Sounds like you need a blower motor resistor located down under dash on pass side next to blower motor. This is a comon problem and I have changed many of them. thats just the fan speed problem. Ive seen the blend doors break easily on those jeeps. thats inside the heaer core box and moves the flap from hot air to cold air. If it is stuck halfway -or mostly to cold- you may only get luke warm air. If they had the heater core out-maybe they possibly broke it.
