HI ALL...
i have a 2010 hatch sti and have just noticed my air-con has stopped working,i have checked the usual...both fuses are ok,the orange light on the heating controls comes on.
i only noticed yesterday when i turned on air-con and the cold air was no colder than standard heater.
when the a/c button is pressed i hear no clicking noise from engine compartment...it seems the solenoid is not clicking in on the a/c pump,have tried swapping a few relays round to rule out relay problem but dont seem to be getting any voltage at the a/c pump plug.
can anyone suggest anything else or has anyone had simular problem,any advice would be gratefully recieved.
thanks....jase

Maybe a leak no gas left

would no gas stop the pump solenoid clicking in...im not that knowledgible on a/c

Not totally sure what you mean by pump solenoid - are you referring to the magnetic clutch??

"The low pressure switch detects a refrigerant shortage and deactivates the compressor (magnet clutch) if the refrigerant pressure is abnormally low. (Because any further compressor operation in such a state may lead to compressor seizure)"

If you've checked fuses and relays then the next port of call is - is there any refrigerant/oil in the system??

Hi I have a similar problem on my 2010 Hatch. After lots of diagnostics. Found that the system has a leak. Which no one can Find so after all the re gassing still no Air con. You may need to re gas your system and check for leaks.
