SOURCE: 1995 cadillac deville 4.9 eng no heat

The heater in your car depends upon a flow of hot coolant going through the heater core in order to get hot air into the car. If the heater core is partially plugged, it will restrict the flow. If you have a head gasket that is putting exhaust into the cooling system, it will eventually get into the heater core. When this happens there is no coolant in the heater core to make the air warm. If the water pump vanes have corroded away the result will be very poor coolant circulation causing the heater to not blow hot air. If your car is equipped with a heater control valve that is not functioning properly, the coolant flow will be restricted. One or a combination of these factors is likely the culprit in your case.

SOURCE: When I push the air conditioner or the heat

There is a problem with the air condition,econ,means the ac is not coming on,check to make sure the freon has not leaked out.If the freon is fine,see if the clutch is engaging on the compressor,if it is not ,then check the sensors on the liquid line ,along the firewall,they can go bad and the compressor will shut down,check all this and get back to me.

SOURCE: I have a 1996 Cadillac Sedan DeVille. This spring...

If the a/c does not engage as a result of the electronic control system in your 1996 Cadillac, the climate control system may need to be replaced.

However, if the problem is being caused by low charge of R134a in the system, have the system charged before changing that electronic part.

I have never seen a Cadillac Climate Control System do this, which leads me to believe that it may be more electronic than refrigerant pressure related.

If the refrigerant pressure was low in the system, the climate control system should still stay on 'auto' mode, I think, and simply blow warm air.

After changing alternator in 95 cadillac deville the heat doesnt blow at all


The alternator does not have anything to do with the blower fan for heat. You may have unhooked a wire by mistake, or you have a blown fuse. God-Bless!

I Have a 95 deville , replaced thermostat and have heat only when engine RPM ran up , nothing on idle speed. Whats up?


Either you are low on coolant or you still have an air pocket in the system after you replaced the thermostat.

With the engine cold remove the radiator cap. Top off the radiator if low. Start the engine and allow to warm up at idle, topping of the coolant as necessary. Once the thermostat has opened, the upper hose will get hot. Snap the throttle a couple of time. This will help force coolant into the heater core and push out the air. Once the cooling fans come on replace the radiator cap.

Raise the engine RPM'S to about 2,500 and hold it until there is sufficient heat out of the vents. Let the engine idle, Id there constant heat? If not snap the throttle a couple more times and then raise the RPM's up again.

Heat not coming out of vents,but heat will come out of the defroster. 95 cadillac


Good news is there is no problem with the heater. Bad news is the Flap didn't open to direct the air flow through the vent so all the flow going to the defroster. Part is not expensive, but labor is a concern since the work is at the dash vent. Cheers
