I know it's hardly the weather for it, but my mum's new car has air con and she's wondering what the basic tips are to keep it working properly.
I know you have to use it every so often to avoid mould buildup leading to a musty smell, etc but I don't know the specifics, i.e what happens and how often you should operate it.
I remember a thread about this a while back on here but I can't find it now.
Tips are appreciated.
Thanks
