over half the aircon vents dont work im wondering if its worth pulling the dash out and trying to fix it only the driver left side and front window driver side is working, behind the glovebox i think the black box there is part of the aircon, it has all masking tap over it.

its been like this since i got the car and only just started wanting it to work lol.

any infomation or advice would be greatly accepted


Thank you for your time
