Mini One aircon not functioning well

Leaks & Noises
Hi, my car aircon blows hot air during normal driving even after servicing with freon filled. At cold, when I turn on the aircon it is cold but quickly it turns hot. The compressor is running but the fan is not. Tested the fan and it works well when the radiator temparature rises. Tested the relays and they are okay. My mechanic found that the aircon pressure is extremely high when the aircon is blowing hot air. Can you please help?

Maybe if this system has an evaporator temperature sensor fitted it,s been knocked off or disconnected that would give that kind of symptom you describe.I would first look at this through scrolling values to see if it,s functioning and compare it with the cabin temp. Sensor value.other than that it,s also possible you could have a blockage if the pressure is excess. High,other thought is a faulty fan module ,but this would normally log a fault code.

the cooling fan must operate to keep the condensor cool this should have been checked when you had the air con serviced thermostatic expansion valve could be faulty but get fan sorted out first

When I switch on the air con and the compressor starts running but the fan doesn't. Te fan will on strat running when the radiator is hot, what would be the possible faults with the fan?

check fuse and relay for fan if not sure how to do it get a auto electrician to check out for you when fan is sorted your air con will work

Hi roverman, we have checked the fuse and relays, no problems with them. Could there be another control / hidden relay that kicks start the fan as soon as the aircon compressor is switched on and is now mulfunction? or could it be just the wiring connectiing the aircon swith to the fan that fails?
