Hi all I have a buick skylark 1971, imported from california to Europe. Now the pre-owner "modified" a few things in the car, for example the climate control was missing when the car arrived and instead of a radio he put something like a "heater" in there. This means that I can king of heating the car, because when I use the "heater" it will blow some hot air. But it won't blow to the windscreen and I also can't use any climate control. So my target will be to recconstruct my heating system as I want to heat the windscreen and also cool them down. First question; any idea what I have to buy to do this? Second; how can I find out if my car had originally an A/C or not? What I bought know is the climate control panel, this one I put in the place where it was empty in the dash. But the "heater" the pre-owner used I want to remove, I also want to insert some heater duct hose, as he removed them also completly.
