service manual. check to see if the lines are routed correct. Also, there is a valve that controls if the coolant flows through the heatercore in the engine bay. check if it is open.

^The valve is inside the car and attached to the air mix motor.
When you switch the temp comtrol to warm, do you hear the air mix motor moving the flapper inside the console? If so, you probably have a clogged heater core. If not, you have a bad logicon/air mix motor. In the mean time, unhook the air mix motor from the flapper door and move it manually. You can just leave it on hot until about March, then figure out what to do with it.
