Where is the blend door actuators on a 1995 Cadillac Deville

SOURCE: 1999 cadillac Deville cold air blowing out passenger side vents

Sounds like a Blend door issue, but could be the controller switch, Test ALL modes of operation to see what works and what does not. That should narrow it down a bit. The Blend doors are flap/ doors that regulate air flow, newer vehicles are plastic - electric assemblies ...prone to failure. Any clicking or thumping noises during switching modes and on-off suggest a bad Blend door. Hope that helps...good luck

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.

THe actuator is usually in the vent housing behind the control panel. You can follow the vacuum lines from the a/c-heater control to the actuator.

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
