Low heat is most commonly caused by a low coolant level in the radiator. I have a 1995 Cutlass supreme that only blows out the floor and defroster vents. I had fixed it once before, but it is acting up again. There is a controler box behind the glove box that controls which vents open up. Two things could possibly be wrong in the area. One....the electrical connector could be loose or dirty. Two....The vacuum hose running to the clear plastic vacuum manifold near the controller box has been cracked or broken or burned through and is not providing vacuum to the vent doors. I know this sounds complicated, but if you remove the glove box door and box liner, the controller box and clear rubber vacuum manifold will be evident. The eletrical connector has 4-6 small gauge wires in it and a white terminal end. The vacuum manifold has one black vacuum hose and several colored hose running from it.

Cold in Michigan


check your climate control that could be the problem not opening all the way, also if not enough hot air comming out coul be the blend door some cars they used to use vacuum instead electricity to change air outlet some times these hoses get cluged theyr conected to the climate control. now try a cardboard in front of the radiator this will give you extra heat.

The heater core gets hot but only luke warm air will blow out on floor or defroster


Check to see if the air coming from the vent is also lukewarm. If it is and assuming the coolant level is fine, the most likely cause is a bad thermostat. If the air coming from the vent is hot, you may have an issue with the blend door which determines air flow.

Defrost blows cold air


Sounds like you have a plenum door that is not opening when you go into defrost mode. You will have to check all your vacuum hoses and switching valves under the dash to see which one is not working. Hope this helps.
