I had the cambelt changed last week. It might be coincidence but since then I've notice the aircon fan under the bonnet hasn't spun at all. I'm sure this has always previously spun with the aircon on. Strange thing is, the aircon still seems to be working, though with this weather it's tricky to check that the icy cold air is actually the aircon working or just freezing cold air from outside. But the windows demist (though maybe not so well as before) and I can hear the very slight gurgling sound of the compressor[?] which goes away when I press the econ button. Can anyone tell me if the aircon fan under the bonnet is meant to run all the time if the aircon is switched on, and whether a cambelt change could have interferred with this at all? Thanks.
