Title: Aircon Not Working - Cooling Fans Constantly Running...?
Post by: daz_rt_04 on May 06, 2016, 07:44:56 pm

Evening chaps,

I've had this issue for a while yet would like to get to the bottom of it.

So, my cooling fans  (Big and Small) are consistently running.. Unless I press the ECON button which stops them.

The Aircon doesn't work either, I'm guessing there is a link here? I've been advised towards the aircon pressure switch..

Any suggestions appreciated.  :happy2:

Would it need a re-gas?

Yeah I had this problem! My fans were constantly on and it boiled down to the pressure switch being faulty as the car thought the air-con was on all the time.

Gas has been topped up recently.

99.9% sure I have. Physically struggling to see the temp sensor connection past the inlet so I can't even check it at the moment. I did a runner flap delete PCV delete decat and inlet clean all at the same time. So it's possibly gone into some sort of safe mode. Hoping to have it plugged in tomorrow

Don't mean to hijack your thread daz sorry haha.
