First check the simple stuff. My '98 temperature **** broke at the little collar that pressed onto the shaft. You turn the **** but it doesn't turn the shaft. Use a little JBWeld, or else the **** is pretty cheap.
That **** turns an electrical control. There's a servo somewhere under the dash, with a cable that moves the actual heater valve. Check whether it's moving. Follow the heater hoses from the engine, one has the valve on it before going thru the firewall. It's close to the firewall, mid-height, sorta forward from the glovebox. That's got a lever that's worked by a cable. Turn the car on first, then have someone turn the heater control back & forth, while you watch for that thing to move. If that's OK, THEN you can worry about the heater core.
And like I said, check for air in the cooling system...
