Defrosters are not working on my 2000 Cadillac Deville

Only my defrosters are not working. The vents and heat work fine and the blower is blowing hot air fine. It just won't blow through the defrosters. Any ideas? Thank you. P>.S. I Just did find a hose that is broken under the hood. Looks like it might have something to do with the defrosters as it is near that area. I tried to re-hook the hose up and it cracked as it is so dry rotted. Does anyone know what kind of hose it is that I need and if it will fix the problem? Also there is a place for another hose to be hooked up and there is no hose around. It looks like it comes out from where a filter is located. Thank you for your help and knowledge. It is appreciated!

Go to your friendly nieborhood auto parts store, you need a 1/8 inch rubber hose to repair that, commonly used for window washers also.

SOURCE: heater control 98 chevy s10 blazer

These trucks have a problem where moisture builds up in the heater box then freezes. When this freezes and you change your heater settings it breaks the shaft for the blend door. If this is what happened you should be able to look under the dash above and to the right of the gas pedal and you will see two vaccuum accuators one of them you should be able to wiggle around the linkage if it is broke. To fix this you need to remove the entire dash to get the heater box out which involves discharging the AC and draining the coolant because the heater core and evaporator come out. Please rate.

SOURCE: Air only blows to defrost

The problem is with the blower door actuator. It's vacuum driven and controls the air flow from the defrosters, vents, and floor. With the AC on, open the hood and check the lines (very skinny rubber lines) at the firewall in front of the passenger and work back ward. You're looking/listening for a vacuum leak, either a pinhole or maybe a worn end in need of repair.

Some cars use vacuum from the engine to open and close the doors that direct the air to different positions. It is possible that the vacuum line to the controls is cracked or disconnected.

How to manually open the dampers


I have a 91 deville that never had a working heater. I fixed the prob by unhooking the actuator, or blend door motor. Now i have defroster, and heat comming from floor, but no vents. The actuator is behind the trap door in glove box, its a black box with a rod connecting to the blend door. After unhooking, make sure the blendoor is all the way to the right, i wired my in that position. Heater works good, and have had no probs. Hope this helps

A/c not blowing 1998 deville


Could be the blower motor or the blower motor resistor. Take the blower motor out, power it and see if it works, if it does then replace the resistor.

If the blower was working why did you replace it?
Heat is made by the engine, and then it is sent into the heater core and a fan, blower motor, blows heat into the car.
First - check that the coolant level is full. If not add MIXED coolant.
Then drive a few miles for the engine to get hot.

If coolant level is full, the thermostat might be bad, or the heater core might be plugged.

1991 chevy g20. 5.7l v8. air conditioning does not work. the blower and switches seem to work fine but it does not cool and only blows out of defrosters.


Blowing out of the defrost is a vacuum problem. You have a leak between the motor and the heater controls. Most likely needs to have the A/C system charged up.
