Heat/Air dash vents has a diverter stuck in the closed position

The center air vents in my dash board above the radio don't blow any air at all. I pulled out the small manual air vents and noticed the diverter in the venting system is stuck in the closed position. How do I fix this so that it operates as designed?

SOURCE: When turned to defrost, no

The vent flap foam lining has come loose and needs to be removed or reglued . A spray on contact adhesive works best , don't glue the flap to the vent casing.

SOURCE: 1986 VW Golf heater blows cold air

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.
if the car is not overheating, the thermostat is working fine.... replace or flush the heater core multiple times to try and eliminate sediment build-up.

SOURCE: Vents only blow hot air

its either the blend door motor or just door is stuck or the switch could be bad to activated blend door motor. Or the the switch is on the heater core lines (outside in engine compartment) may not be functioning but I think your car is too new for that option.

SOURCE: my heat not workini but blow cold air where is

Has the car been changed coolant since it was bought? If it is time to change, let do a flush through a heater core. There are 2 coolant hoses going thru a fire wall. One for coolant in and one for coolant out. Heater only works if coolant is flowing through the heater core. Therefore, there are one or both following cases contributes to the problem: 1-If the valve control coolant flow gets stuck, then it always closes  so there is no heat. 2-If the valve is working, but the heater core gets clogged up, then there is no heat.

I believe you are correct. The cable running from the thermostat control knob to the vent lever can disenguage from the vent assembly. You can remove the plastic side panels below the radio/heater housing to see the cables. Move the heat/cool knob back and forth to locate the correct cable and see if it has fallen out of the vent assembly.

Air will not come out of a/c vents


Your controls are vacuum operated. Make sure that there is vacuum present...if not find the disconnect. Or, the vacuum "motor" that controls air direction has failed or is stuck.

I have a 1999 VW Passat. No heat blows from the floor vents or the rear passenger vent. The heat from the dash blows strong and hot with no problem. What could be the problem and could i make the repair...


These vehicles where prone to heater core failure. It lives in center of dash against the fire wall.

When this repair is done at the dealership, the tech is paid only 6 hours. The job takes 10 to 12 hours.

So, what does he do?.....he doesn't put everything he took out back again, which on this job would be the ducts that are along side the 'transmission tunnel' to the rear vent.

Ergo = No rear heat .

On the other hand, it could be the system is stuck in Default..'Windscreen vent priority'.

2003 Grand Prix not blowing hot air. Does the heater coil need to be replaced? If so where is it located?


If the heater coil was bad, it would be leaking radiator fluid... probably into your dash/floorboard (depending on where it is installed in your model car). There is a switch that diverts the hot radiator fluid through the heater coil when you want heat. There is also an air diverter valve that helps to mix the hot and cold air. The fluid valve is controlled by the A/C settings control. The one that you use to choose between heater/air conditioner/vent/ defrost. The air diverter is controlled by the temp mixing controller. The most simple explanation is that one of those valves or the controller of one of those valves is not working. If the hot water cant be diverted through the heater coil, the coil can't exchange the heat (warming the air). If the air diverter (hot/cold controller) cant move to add heat, then all you will feel is air from the vent side (from outside) or from the A/C cooling the air.

I would guess that its either a controller or one of the valves themselves. Odds are, it is a controller. That tends to be what malfunctions first.

Hi , i have the compack 316i 2 door , i have a problem with the engine ( hot air ) coming into the car while driving .


If your climate control isn't set to "vent" then your blower valve (on the heater core) is stuck, and should be cleaned/replaced.

Heater blows cold air. Vents work fine. Used the heat, turned the vehicle off and back on and heat no longer worked. Checked coolant and fuses. Turned all dials and nothing worked


Could be that the thermostat stuck in the closed position, which is preventing the coolant from getting to your heater core. Cheap part to replace and a good first step.

Heat blows out driver vent when ac on


this problem is caused by a defective air temperature control blend door actuator motor, it is about center of dadsh in air ducting, it moves the door that diverts air for cold from ac or hot from heater, you must remove the dash to repace it, about a 15 hour job fotr a home mechanic with a factory repair manual, nearly imposs without one.

Climate control system only blow air out defrost vent


there is a good chance that you blend air door is stuck closed over your heater core and therefore not allowing the heat to flow, also your door that opens and close your direction of flow from the floor ,das,vent and defrost.your going to have to remove the lower cowling of the dash on the passenger side analso some of the center dash to actually check to see if the cable,servo motors. are acuating the doors.the issue could be just a stuck door or a misaligned cable or that it came off. that falls under the mechanical side of probabilities. electrical would most likely be a faulty selector switch or a servo motor
