Opel Omega - electronic air conditioning problem

dak

Hi

While travelling down the country for X-mas the AC turned itself off any time the car was at idling speed. When moving it was fine and heater /demister etc worked. Sat in car today and have no heater or demister etc- the illuminated switches for these has gone out. Checked the fuses which are ok anyone any ideas ? Will have to leave to a garage in new year but wondering if any mechanics have any idea what would cause the problem ?

I'm not a mechaninc but I had an Opel Vectra with climate control air con once so I am guessing that it is a similar system in the Omega. My climate controled air con stopped working one day like yours for no reason. It went back to the Opel garage where they could not diagnose the problem other than the whole system needed to be replaced. Car was outside of warranty and they wanted something like £400 at the time for fitting the new system. Easy to say that I didn't get the system replaced and traded the car soon afterwards with the climate control still broke.

Don't know if you have the same problem but I found that the Opel garage was utterly useless in diagnosing the problem. Instead telling me it needed to be replaced. I read somewhere later that it is a fairly common failure on Opels. Hope you have better luck than me. A good auto electrician might be able to help as the problem sounds more electrical than mechanical.

"When moving it was fine" Does this mean it dissengages in neutral?

No. When engine was at idling speed it was as if there wasn't enough electrical current and it tripped out. It now doesn't work at all.

So it sounds like electrics then, oh dear! Dunno the system but most climate control have a error code read-out which can be accessed by those in the know (try googling UK Vauxhall sites), it ciould point to the problem.

Thanks for the help - problem fixed! I hadn't physically checked the fuses as the manual said it was on the same circuit as the heated front seats which I thought were still working as the on light came on when switched . Seems daft that an on-light illuminates when the heated seats are not actually working. A UK vauxhall site advised to chaeck fuse 14 which I did an replaced for the enormous sum of 50 cent!! Demisting again horray !!!
