94 TC Heater Core

Where can I find a diagram that will guide me to removing and replacing the heater core for a 94 Town & Country?

I am getting cold air out only when the temp gage and the coolant levels are normal.

I am assumong that the core is blocked....

Can anyone help?

Thanks

Ken

Don't assume. Check it. Disconnect the hoses at the firewall and poor water in the supply tube. If water doesn't run out the return tube at about the same rate, it's blocked. If equipped, is the on/off valve attached to the temperature control lever working?
