Cadillac Repair: 95 deville no heat, heater core, glove box

Question
My 95 Deville blows air when the heat is on, but the air never warms.  Any suggestions.

Answer
Your problem is most likely a fault of the AC/Heater PROGRAMMER located on the passengers side under the dash just below the glove box. Make sure that your heater hoses going in thru the firewall at hot to the touch and that the heater core is not plugged up.
