Nothing coming from the vents when you turn on the a/c, heater, or defroster


You can jumper the fan motor to make sure it runs and if it does then look at the switch or resistor. You can also remove the resistor and omh acrossed it to make sure that it hasn't blown the fuse on risistor.

Climate control system blows only through the defroster vents and not through the passenger compartment vents; the windshield fogs in high humidity and windshield wipers are necessary to clear the fog. ...


If the fogging is plain moisture and not coolant (it would take on a green hue and you would smell coolant if this is the case) than the issue is with the blend door actuator. This component diverts air from the window, to the vents and floor. You may have a "stuck" door or a defective blend door. If it is coolant you are seeing (smelling), you may have a bad heater core. When bad, a heater core will dispel green vapor through the defroster vent.

Assuming the problem is merely the blend door, you may be able to free the part (if it's stuck) by locating it (usually under the glove box or between the glove box and middle console.

When I cut on my air or my heat it will not blow out the vent but it will blow out the defroster what is the problem 1995 Catilac sedan Seville


One of you motors in the heater venting system has burnt a fuse, burnt out or has come disconnected. This prevents a flap in the heater from changing positions and sending air to the floor or the defrost.
Have you had a heater core or motor replaced recently as the heater ducting needs to be removed for some of this work and it is possible to have problems with the heater venting doors not moving after the work is done.

My 97' VW Jetta's defrost won't work. The heater works great, and blows plenty of air, but nothing comes out of the defrost vents. Does anyone know what it could be?


In the engine bay near the firewall there are a few small rubber hoses that join to small plastic hoses they all just push onto each other make sure they are all on and none of them are cracked or perrished

Blender door not working correctly on 2003 grand Marquis. Bows out defrost but not vents. Occasionly out the vents but not often


not blend door, blend door is responsible for mixing hot air from heater core side with cold air from evaporator side of the system. you have a problem with your panel doors it may be an electrical problem with signals from you heater control module or a vacuum problem or you may have damaged components inside your dash. your vehicle will default to defrost setting automatically if there is a problem in the system

Sounds like the flap valve in your vent system that allows air to go to the defrosters is either jammed or broken. Unfortunately you will have to take the vent system apart to look.

My 1998 Subaru Legacy defrost is stuck on defrost. None of the other control buttons (vents, floor, floor + defrost) work. This is an intermittent problem.


probably whatever you put in the cupholder has spilled on the controls causing them to stick,poor design isn't it? no real fix ,i would try to spray some silicone in between the buttons and try to free them,look into buying a unit from the junk yard, not a hard component to change at all
