ok im looking at buying a 156 2.0 ts.

anyway, looking over it today.
noticed the air con pump aint working/clutch not kicking in.

how cold should these air con systems go? as cold as any other car/make?
first things to check for the air con pump clutch?


also in the back left corner of the engine bay as you look at the front of the car
there was a noise, some tihng like a bearing going when the car was cold for a few minnutes/maybe 5.

prob not the water pump, as thats onlt been done about 2k ago. any ideas?

thanks

I have got a 2004 156 1.6TS and the aircon is crap compared to other cars i have had. Actually that is probably a bit harsh but is definately does not get as cold as the wife toyota or my previous VW's. I am pretty sure there was a link on here before about the air con and its effectiveness. Apparently "they all do that sir"

Yep, I started a thread last summer about this. The air-con/climate will struggle to cool the car if the outside temp gets anywhere near 21 degrees c /70 degress F.

To get the most out of it, hit the air-recirculate button. It's stil pi55 poor though

The 159 system had better be A LOT better!

Not too sure about your other question though.

does any one know why the air con pump might not be kicking in?
as the air con pump clutch wasnt kicking in at all.

I have just bought a 156 and looked at about 10 156's over that time.

About 8 out of 10 had what I would call weak air con, the other 2 were much colder and pushed a fair amount of air out (though not as much as an equiv audi/bmw). Might be worth having the Aircon serviced?

My 156JTD was always fine & neve felt weak, although its a common complaint about 156s.

Wife's 156 1.8 from 1999 was never quite as good as the Xantia she had previously but not terrible. It is getting towards needing a re-gas now though. There's a low pressure cut-out switch in the system so if the refrigerant pressure drops below a certain value, the compressor clutch won't energise. I think it's most likely you've lost the refrigerant or the pressure switch is faulty.

The pump will not kick in if there is no or very little refrigderant in the system.

The air con won't kick in below 4 degrees, so maybe it was a very cold day when you were looking at it?

If it never kicks in it may well be the relay which switches it on that has gone. It happened on my wife's 145QV last year, but haven't heard of it happening on the 156.

The 156 air con is not great, but you should be able to tell when it's on!

Please help, I tierd of wiping the windscreen and freezing my but off. Any help would be much appreciated

If no airflow i would say the fan in knackered. Someone will be along to let you know for sure soon.

Sounds like more than one fault. The aircon not "ticking" could be low gas pressure in the system or, as has been said, a cold day. The lack of air could be the fan - can you hear it running and does it's speed change with the fan speed control on the dash? If you're freezing, it also suggests the possibility of another fault. First thing would be to check the fuses. Can't remember which one serves the heater fan but an easy first check.

Thanks for the replys. I checked the fuses and they are all ok. Wondering if anybody knows,Is the air con and the internal fan a intergrated unit? . Bit of a concidence the both seem to have gone wrong at the same tine!! Also thinking of taking the car to an independent garage. If the fan is knackered any idea about the cost of a replacement. Thanks again for the advice Tony

I'm having trouble with the aircon in my Spider. I'd recomment you go to a dealer (anydealer) and get it charged/tested. It will £30 well spent to find out what the prob is/isnt. You can decide how to fix it. On the Spider the fan should switch on to setting 1 automatically when the air con is switched on. If the fan isnt working try fuses but its prob the resistor pack on the fan.

I work out in the semi-desert on the West Coast of South Africa, and i can promise you my aircon deffinitely works. It only feels a bit sub-standard at around 40 degrees C if your engine and vehicle speed is low. The engine drives the compressor, and movement of the vehicle cools the a/c radiator.

It gets pretty hot out here, so a working A/C is essential. Perhaps you should have the refrigerant checked out?
