Default Aircon behaviour

Hi All,

I just bought a second hand C5 and noticed that the aircon is not cold immediately after starting the engine. The fan is running but the air is not cold. It takes about 3-4 minutes after starting the engine for the air to become cold. And I am not talking about after the car is parked under the hot sun for a while, it is the same even at night when the weather is cool. Is this normal behaviour of the aircon?

No. Usually, the compressor (made by Sanden) lasts abt 6/7 years. When it is weak (cold when car is moving, but not cold when stationary), it is due for replacement. A $1100 job (replace both compressor and condenser) at TnP or Mike's workshop (both are CitroŽn specialists). Or you can get your second dealer to cover the cost, depending on your contract.

I was told that If totally no cold air at all, it means the compressor up lorry. If you do not want to change both the compressor and condenser at one go, maybe can start with the condenser first.

Regardless, do ask them to check first before start to do replacement. Who know it is just your aircon has not sufficient then just top up ok liao.

Happy motoring

When change compressor best is change condensor also

If u change either component alone

Its just going to dirty and kill it again

Get them to do a full vacuum of the system. Then refill the gas by weighing... Not via meter reading... not accurate.

I see. Thank for sharing. This is a good way to fix the problem for sure. A bit like dealer workshop style ya.

If lower assembly faulty, best to change the whole higher assembly instead.

Mechnic happy beco less work, workshop boss also happy because total bill size also bigger a bit.

If outside workshop no have, maybe can try dealer workshop. Usually they have more pattern but will need to pay more as usual.
