A strange "rattling" noise can be heard from underneath the body of the car when A/C (air condition) is active/used (e.g when the AC button is lit (red LED)).

The A/C works fine and it's as cold as it use to be but the noise is something "new" that I haven't heard/noticed before, and, maybe that has to do with the last couple of days which have been quite hot?

Please tell me this is an easy and relatively cheap fix? ;)


Thanks!

I actually nailed it down. It's a pipe-holder that is loose (probably missing a screw and a nut) so I will check with the workshop about parts and possible help. It was visual when the car was in idle/neutral by looking underneath, the holder was rattling in sync with the noise.
