PLEASE help with A/C question!
It is green single wire connection. Make sure you have the right one and you are running 12V jumper to the compressor and not back to the car.
What does your outside temperature read?
You need 3 things for this... A computer, usually a laptop (doesn't have to be fancy you may be able to find a cheap pentium I or II on ebay for under $50).
A cable that connects to the car ( a few places sell them but I'd recommend rosstech since you will also need the software)
As I mentioned, you'll also need software ( there is a free version to check and clear codes but it is very limited)
Link should explain it all.<ul><li><a href="http://www.ross-tech.com/vag-com/index.html">http://www.ross-tech.com/vag-com/index.html</a</li></ul>
