Hello,
I have a banging behing glove box when and only when I shut the doors with windows up. Also I get hot air from left vents and cold air from right. i know that on models with sat nav RCCM is located behind glove box. Could this be banging..? Is it a possibility the connector been disconnected hence clima not working properly?

 

if your getting hot and cold left to right that would indicate a dccv issue . and possibly the rccm has a burnt track but that does not always happen .
it sounds more like the heaters recalculate/fresh air door in the heater intake is flapping to release the cabin pressure caused buy closing the doors , normally it would not and the cabin pressure should escape from a flap in the left rear guard behind the bumper so probably two separate issues there ! id start by checking the cabin pressure release vent in the boot/trunk is not sealed for some reason , and check the servo is connected to the fresh/recirculate door . then start on your dccv issue.
