HEATER NOT BLOWING HOT AIR

2000 Jeep Cherokee

Heater problem
2000 Jeep Cherokee 6 cyl Two Wheel Drive Automatic 113950 miles

My temp. Gauge is overheating and my heater is not blowing out hot air only cool air when the heater is on. The A/C works fine. I changed the thermostat and the coolant. What else could be wrong?

Sounds like a bad head gasket. Does the cooling fan come on and stay on while its overheating?

Sounds like head gasket. To know for sure have it tested for exhaust gases in it.
