If I understand correctly, the temperature gauge will read in the "normal" range, you slide the temperature lever to "hot", but you still get cool air. If that's correct, there was a common problem caused by rust buildup on the pivot for the temperature blend door. The door sticks in one position, but the temperature slide **** appears to be working. In fact it is not. The cable attaches to the door's lever through a three-fingered clip. That is the self-adjusting feature, but when the door binds, the cable just slides through that clip and doesn't move the door. The clue is you won't hear the nice "thump" when you move the lever fully one way or the other. Another clue is the two heater hoses going to the heater core will be hot. If that sounds like what you have, I can describe the repair procedure. You'll need a rag, a can of spray oil with a stem, (Chrysler's "Rust Penetrant" is recommended), a can of "Spray White Lube", (also from Chrysler), and a drill and about a 1/8" drill bit.
