My 2000 jimmy has heat problems. the heat goes from cold to hot to warm to cold etc. what could the problem be?

If the temp gauge is now more stable, the problem is in your heater system, not the engine cooling system.

When i get in my jimmy to go to work its blowing hot air( with the heater on of course) and then there is a creaking noise coming from the blower motor area, then the heater will start blowing cold air...

Because the Main Gear in the Blend Motor has cracked or teeth have chipped and is now not keeping the heat/cold door to the Hot position. 3 fixes: Buy a new Blend motor, takes about 5mins to replace. Buy a new Blend Motor Gear, will take about 30mins to fix. Repair current gear with Epoxy, takes about 30mins and 12hrs for the glue to set up strong enough to use it.

You have air in the system, you will need to work that out, some engine have cooling systen bleeders, if not loosen a heater hose to bleed air from the system.
