i have climate control, but this shouldnt affect the vents, as they can be closed anyway without causing a
problem, or isn't that what u mean?
I mean that on my car the manual climate controls are on the lower part of the dash, but for example on
Ibiza Evo 2's pics teh automatic system is right under the vents, so the method from taking a part the dash under the vents is bit harder.
I took of my cd/radio and the box under it. Then the plastic casing surrounding it and the climatecontrol unit (see 'em all
here)
comes off after few screws, two on both sides, and one inside it 'on the roof'. I have pics of these, but not available on the moment. Then you pull off the whole thing and de-attach the wiring to emergency signals and such. From under there you can easily reach and take off the vents without any 'violence'..and almost without..
