Mk3 Aircon Light non-responsive


Recommended Posts



Throwing this out there for anyone who may know. Recently the ac & recirculate buttons on my focus (2012 Mk3) stopped working. They usually light up when pressed, but no light and no function. Fans work fine tho.


Checked the fuses (all 3 locations), all looked fine relating to aircon.


My mate said the gas might be low; but it;s only been running for 5 years and I have no warning lights. Is that possible?

Hey @iantt,


Thanks for the response man. Yea that's what I was thinking, which is why I'm thinking it's not just low gas.


I remember checking fuse 85 in the passengers footwell, but not 77. I'll check it later today and let you know

I would definitely check the refrigerant level you may have a very small leak  .low level can cause exactly the symptom you have on any car try this first else you will be going round in circles chasing your own tail. I have had no lights on no run with other cars new gas fixed it. If your aircon fans are running you may have a little gas in the system but not enough to fire the system up.
