Mk3 Aircon Light non-responsive

[subressor]

Hey,

 

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?

 

Cheers,

they should light up regardless of how much gas is there.

have you checked fuse 85 and 71 in passenger footwell fuse box?

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

Not 77, 71

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.

Thanks Gizza, how would I check the refrigerant level on this car?

 

FYI; I checked all the fuses above and everything was fine

what type of air con/heating do you have ? electronic auto temp control or manual control with knobs for blower/temp control?
