Air Conditioning Not Working After Cam Belt Change

[B19LYB]

Hi All,

I had my cam belt changed recently and shortly after tried to use my A/C and found it wasn't working. I just assumed it had run out and went to get it refilled, i was told by the guy that i had a leak....

Symptom is when i turn it on the light comes on but you don't hear the usual sound of it starting and no cold air.

So i was just wondering does anyone know if the A/C needs to be touched at all during a cam belt change or maybe what has happened? The garage of course say that they didn't touch the A/C but its a coincidence it only stopped working after i had the belt changed?

Any help would be great

Thanks in advance

You need to remove the front belts, which includes the A/C belt, to do the cam belt.

Do you think they forgot to connect something or disconnected a pipe?

It was working fine before the belt change.

Is it possible to diagnose the fault myself or best to take it to a specialist?

Thanks

When I had mine done they couldn't get enough leverage without faffin with the air con, which meant they undid stuff and my air con needed re-gassing too, they did that for free tho maybe yours was similar but they just left it?

Check all electrical connections to air conditioner components, I have had several customers bring their cars to me with non functioning aircon following a service or other work only to discover that a plug on a pressure switch or compressor itself was .....errm.... lose.

I'm currently replacing the cam belt on My IS, the only three electrical connections that need to be disconnected are the two fans and the sensor at the bottom of the radiator. The aircon system does not need pumping down and no pipes need to be disconnected. The drive belt needs to be removed from the compressor but that should not give a problem, but just have a looksee to make sure that the belt is on the aircon pully.. It is possible that the car is at an age where the increased pressure from running the aircon is just too much for the elderly condenser and the system has corroded and leaked..... The Winter road salt plays hell with aluminium.

If you can find nothing obvious then I'm afraid that you are in the hands of an air con specialis, try to find one who knows what he is doing, I find that most mechanics know jack about aircon other what they have learned on a one day course
