A/C will only blow through defrost vents


Common question on this site. On late model cars, the vents are controlled by blend door motors. Small electric motors open and close doors to direct air flow.
Chances are you have a blend door that is stuck or a failed motor.
The default position is the defrost to make sure the windshield is always clear.
Someone will need to look behind the dash to see if all of the doors will move on demand.

I have a 04 galant. The heater won't blow hot air. Went to a repair shop and they said it was temperature control (the control knobs in the car). Replaced that and it still doesn't work. What else can it...


It does blow correct? Just not hot air? This shop replaced the control head (the unit that the knobs are connected to)? I'm assuming the answer to all is yes. There may be a jam. Not too common but I've seen it a couple times. There are doors within the air box under your dash where your blower motor and heater core are. The control head controls these doors, opening one vent door to outside air and/or to the evaporator, closing the other vent door to the heater core or vise versa. It also controls the doors which direct air to certain ducts that will blow out the selected vents. If something has been droped down through a vent and worked its way to these doors I'm talking about, it could jam the door closed that goes to the heater core, preventing heat from blowing through the ducts.

I have a 93 Saab and my vents aren't blowing heat. When I hit a bump in the road it may kick my heat on full blast for a couple of minutes, but as soon as I hit another bump, the heat kicks off. Also, the...


You don't say whether the fan starts and shuts off with the bumps, or the heat goes cold but the fan stays on. If it's the fan shutting off and coming back, you most likely have an intermittent connection to the blower motor somewhere at the fuse box, the fan speed control switch or the fan motor, or a loose ground connection at the fan motor. The fan motor is visible under the right side speaker grille on the dash. Make sure you re-connect the short black corrugated hose to the grill vent or you won't have defrosting on that side!

The air distribution rotary switch controls where the air goes. The fan speed switch controls exactly that: fan speed. the temp rotary switch controls the coolant temp into the heater core. You need to clarify what you mean by "Also, the dash controls for the vents won't allow me to turn up the power"

You might also have one or more of the following issues:
  1. is you vacuum tank properly connected and are there no leaks in the vacuum piping? The tank is in the driver side rear wheel well below the trunk deck on a convertible, and in the passenger side front fender area on the other cars. It's a white bottle with one or two hoses connected to it. If not properly on, your vacuum operated heater flaps won't move. Does the air distribution knob make sucking or hissing noises when you set it to different positions? If not, check the tank connections, look for vacuum line leaks, then suspect the vacuum valve behind the distribution knob.
  2. if the air distribution rotary switch makes noises when you change its setting, but nothing happens, then suspect the vacuum solenoids that open and close the heater flaps - could be a loose vacuum line or a defective vacuum solenoid
  3. the shaft connecting the temp control knob to the heater valve behind it may not be properly in place. This can be inspected, and adjusted if necessary, from the left side speaker/vent cutout on top of the dash. Make sure you re-connect the black flex hose to the air vent tube, or you'll get no defrosting afterwards!
  4. remember, the centre vents always blow cold air; a brilliant idea from Saab so the driver (and passenger) can get fresh air in the face and stay awake while the rest of the driver, passenger and car is toasty!

My heater stoped blowing hot air.antifreeze level


If the blower is blowing air just fine, but you cannot control the temperature, you need to listen to air coming from the vents while turning the temperature from hot to cold. If you do n ot hear any change in airflow, then you may a temperature door in the dash broken. this is becoming a common problem on the Equinox and Pontiac Torrent,
