Mine seems to have been very reliable. Gives out cool air in summer and has never been re charged in its life.

Gave the mother in law a lift yesterday and she said that the fan was blowing cold air on the left central vent (and it was ) even though the climate was set to Auto 22 on both sides and the outside temp was around zero C.

I got to wondering if internal flaps or valves got stuck perhaps through not being used in a range of positions. I am not looking to tear the car to bits to fix it(far more important stuff to do on it) but just wondered what sort of problems you get with air con on Omegas hence posting in car chat.

Yes it was fully warm (175 mile round trip) no it wasn't on ECO. I don't often use ECO.

Yes it was blowing hottish air on HI but still with cold. I just closed the central vents and reduced the fan to 3 and the problem was less noticeable or not there.

Actually it has just occurred to me that I changed the HBV last week and it may have an airlock. It all worked OK on the day of the change but it wasn't bitterly cold then!

try the re set procedure. Sometimes the vent motors get themselves in a pickle.

Press and hold off and auto together until you hear the motors start buzzing. On my old pre face lift you could do this at any time provided the ignition was on. But my current face lift seems to only allow it when ignition is in position 2, engine off.

Re hbv, i would be suprised if you have an air lock after changing it as the system is self bleeding,  although giving the main pipe from the rad a good squeeze and burp with the cap off wont do any harm when cold. I would think all vents would be cold if you had a coolent circulation problem.
