Question about 1992 Subaru Loyale

1 Answer

Climate control switch broken

The control is stuck on the heater position, meaning pressing the other buttons (BILEV, windshield, A/C) doesn't switch the air direction. I believe this switch works by compressed air so I may have a leak. What is required to fix this?

Check all the vaccumn lines that might go to the location of the switch. You can pull them off, depending on where they are at.But be careful to notice where you took them off from. and close one side with your finger and blow through the other side.If any air is leaking you have found your problem. If not , it may be the valve itself.

I have a 2003 Ford F-150 FX4 5.4 and the AC only blows out of the defrost and help


Dustin, Sound like vacuum loss to position switch. Defrost is the default position when vacuum is lost in vent control system. Check any and all vacuum lines and connections under hood first, especially any that run through firewall. Check the attached links,instruction and guides, Good luck

How do I get the windshield & the windows defrosted? What buttons do I press?


Does your heater fan turn on? If not, could be a fuse, could be fan motor, could be wiring connections. If heater fan works then defroster switch may be the problem, or connections to the switch, or again a fuse. Temperature controls may have some effect. Usually, defrost needs heat to work well. The engine needs to warm up.

1998 dodge intrepid auto climate control. My heater will not turn off, and the fan is stuck on high, and also stuck on the cold temp. I replaced the climate control module and checked all the wiring....


the fan speed control not adjusting usually means the 'resister' is no longer working. Stuck on cold means the 'blend door actuator' is no longer functioning.

Heater switch replacment


Hello! it's my job to make things as easy for the customer as possible...Therefore I must ask why you want to replace the heater switch? Is it because you have lost one or two of the switch speeds? Your vehicle is noted for loss of the Blower Motor Resistor...
Changing the Heater switch means removal of the Climate Control Assembly which is not the easiest of jobs...I've included the process...But are you sure the blower resistor is OK? If you have lost 1,2, or all blower motor speeds it's more than likely the Resistor pack. And a lot easier to change...

My ac was working fine then one day it stopped and now only hot air blows out the mechanic said the ac is fine and works good but there is a vent door that switches the ac to heater and he said it was...


There is a blender that controls the air flow to go through the heater core for heat, and the evaporator for AC. It very well could be stuck.

You maybe able to try and get it to get unstuck by running the cars AC and switching from heat to AC back and forth and see if it gets unstuck. Just turn it on full blast and go from heat to cool.

If that fails, then you may need to service it. There should be a Lever Marked VENT under the dash, usually by the Brake and other pedals on the Driver's Side. Close the VENT and that will stop the Air from coming in and leave the A/C Blowing through the outlets(Vents).

I also read this online if you have an electronic climate control. "On climate control press off and heat button and let go quickly. Then press automatic. The display will start rotating eventually displaying a code 025,125 , 024 etc. Then press defrost to stop. You may hear blend door operating atb that time. It worked for my climate control."

When i press the ac button it blinks three times but does not turn on. 2007 Tahoe LT


If your vehicle is equipped with automatic climate control, this should help.

Recirculation Operation
The HVAC control module controls the air intake through the recirculation actuator. The recirculation switch closes the recirculation door in order to circulate the air within the vehicle. The outside air switch opens the recirculation door in order to route outside air into the vehicle. Regardless of the blower motor switch position, recirculation is available only in the panel and bi-level mode switch positions. Including the OFF position. The mode switch must be placed in either the panel or bi-level position before the blower motor switch is placed in the OFF position. In order to reduce windshield fogging, outside air is circulated when the mode switch is in the defrost or defog positions. If the recirculation switch is pressed into the ON position when the mode switch is in an unavailable mode position, then the recirculation switch LED will flash 3 times. If the HVAC control module detects a fault with the recirc door the HVAC control module will try to drive the actuator for a predetermined amount of time, to outside air, which is the defaulted position for the recirculation actuator

2004 chevy tahoe, dual climate control, blowing different temps


Its more then likely the temp door broken or temp door motor broken/stuck. There is 2-3 of these motors under the dash on the side of the evap/heater core box. Some require extensive labor to replace, good luck

Volvo v50 2005 climate control puts out heat on driver's side and windshield when AC is on or temperature control is at low. Passenger side puts out cold air. Both sides of climate control are set at low.


I had the same problem. AC computer forgot where the adjustment flaps are.
- Start the car.
- Press Auto button on the AC (if you have this option)
- Increase fan speed (make shure it is not on minimmal setting)
- Decrease the temperature setting to the minimum -> "Lo"
- Wait about 10-20 seconds
- increase the temperature to the maximum -> "Hi"
- Wait about 10-20 seconds
- Set the temperature that you like.

With this procedure you force the AC to move the temperature regulating flaps to go to both end-positions and motors get calibrated again.


If this does not help, there must be a bad contact somewhere or the fpals may get stuck. -> repair.

Can't change air flow direction on ac/heater control. Only blows up to windshield.


It will be a cable that will be disconnected. or broken. Youll have to take some of the dash apart to see the cable and follow it to the switch. Dont be affraid to take some things apart and when you cant see, use a mirror to help you see behind the dash. work the control and watch the action. You will fix this dont get frustrated. good luck

I can't change the air temp from hot to cold air. Hot only.


the first thing to d is to go under the hood and see if eh cable is stuck if it is not then it has disconnected from its position secondly yu may have a heater control valve which is broken inside which means the water is still flowing nd the heater is on wheher o choose hot ot cold.

the only way t fix the heater control valve is to repace it
