NO HEAT

2003 Hummer H2

Heater problem
2003 Hummer H2 V8 Four Wheel Drive Automatic 87000 miles

My Hummer's climate control temp. Control on the drivers side is eratic when setting in cool to cold weather. The temps go up and down when trying to increase the temp. Also there is no heat. All other functions work properly. I do get hot water to the heater core as per a temp check of the hose going to the heater core in the engine compartment.
