Its that time of the year when the suns getting hotter and the Omeegah's aircon will be getting called upon and i think its not working,i got a pressure tester and the psi was approx 40psi on the low pressure side. I don't think i can hear the ac commpressor cutting in,is there anyone who knows the crack about the ac on the big omeegah's ??

thanking you in advance   

hi Chris,i checked with a specialist ac pressure gauge that theres gas in the system and with the ac on i can't hear the pump kicking in and out,that leads me to beleive the pump in nackered. Could do with knowing how to test a pump as i guess the vauxhall code reader won't do that ? 

The recent warm weather reminded me that the A/C does zip in mine, too..

Omeegah - where did you get the pressure gauge?

And one for Kevin - does the Tech2 have any sensors to query on the A/C system (like charge pressure sensor, clutch solenoid operation)?

So am I, wim gassed mine up & they had to free the clutch on the compressor. Worked for a couple of weeks then stopped working.
The pully with the 3 bolt heads is spinning round but dont know where to go from there
