Easy Fix:

Bring a new thermosensor that is placed in the Evaporative core.  In doing so, you have to remove the Evap core out of your Subaru. And thus, it will partly remove the dash units on your passenger seat. That said, you should replace the expansion valve as well.

The newer Ac systems (2005 and up):

The low charge might impact on the air conditioning operation.

Often, we feel depressed while there are issues with our car’s air conditioning system. But the true fact is, we should take our ac for servicing at least one time every 4 years. 

Why to perform servicing after a time span?

• An ac may lose some of the refrigerants. And it may be replaced with air. In this way, there is moisture in the ac. Then, it systematically goes away through evacuation.  
• The air conditioning system has to be re-oiled and recharged with refrigerant. 
• Overall, proper maintenance will assure the air conditioner to operate firmly.

How To Troubleshoot The Subaru Outback AC Compressor Not Turning On

The Air conditioning issues of a Subaru Outback are very correctable if you know the process. However, this is such an expensive task if you go for professionals.

Good thing is, you can save both your time and money by maintaining some DIY tasks to solve the problem yourself. By maintaining the below steps, you will be able to know why the air conditioning is not working in your Subaru Outback.

Step 1

First of all, make an inspection of the controls. Be careful of choosing the air-recirculation button rather than the air conditioning button. 

Step 2

Turn on your car engine as well as turn the air conditioning on. Set the range from bottom to up. Try to hear the concurrent sound to rise while it’s turned on high. In fact, the sound comes from a blower fan.

When there is not a typical sound, then you may need to replace the blower motor.

Step 3

Get to the blower motor. Remove the blower motor from the pad. It should be removed after pulling apart the negative battery cable, as well as reducing the screws.

Step 4

Check the pilot lights in your Subaru. When the lights are not functioning properly, then go for the control panel or control cables to check.

Step 5

Get the control panel by doing the below tasks periodically. 

1. Disconnect the negative battery cable
2. Remove the console box
3. Set the temperature to “Fully hot” 
4. Disconnect the temperature control cable
5. Remove the gear selector trim panel
6. Unscrew the panel cover
7. Removing the radio bracket.

Step 6

Check the control panels of AC as you can see whether they are functioning appropriately or not. Let say, check whether they are running with a good amount of resistance. Or, whether they are ending in the right spots.

When you find something wrong here, then there is a fuse problem.

Then, check the fuse box of your Subaru. You will get it by unlocking the driver’s door and gliding the part close to the floor to the right side.

You can compare a fuse box with a computer motherboard including numerous colors of plastic fuses within it. Exclude the fuse with a pair of pliers. Then, bring a new fuse in that place.
