Unusually for me I actually disabled my aircon the other night using the EC button.
With the windows down I noticed that there was a whirring noise from the engine bay. This vanished when I turned the aircon back on.
I assume that this noise is because the compressor pulley is freewheeling and is in need of some lubrication.
Is this likely and if so how should I go about lubricating it?
