Recently had a double din conversion done and now my air con is acting up. Air only comes out of the vents when the econ button is lit up. The fan still sounds like its working when the econ isn't on bit no air comes out the vents. The air con pipes under the bonnet are still cold if the makes any difference. Can anyone help as I'd like to sort it quick if it's an easy fix now the weather's warming up. Thanks for any help in advance.
