Since you have already tried the obvious look to make sure that the new switch is properly engaging when you move the pedal. Most of these switches have some adjustment in their placement. Otherwise search through the wire harness and tape up ANY cracks or breaks in the plastic coating. Also look at all the connectors for green corrosion. If you find or suspect corrosion replace the connector. VW''s are picky when it comes to corrosion and breaks in wire insulation. Hope this helps.

You should never connect a 12volt to the compressor solenoid.unless you unplug it first, because on some cars the ac solenoid is driven by an electronic circuit. Semiconductors are very sensitive to excessive current. I once had to repair the computer on a mercedes because the other mechanic did that. Luckily I know how to repair electronic circuits, or they would have bought a 500 dollars computer the little chip that blew only costed a dollar fifty cents at radio shack,.LOL. Anyways back to your problem, Have you checked if there is a leak, and all the refrigerant might have leaked out? This would prevent the compressor from coming on. Along the ac line there is a switch, sometimes by the reciever drier, when the system looses refrigerant the pressure inside drops and that pressure switch disable the compressor. , and the compressor wont come on. This is to protect the compressor, because it will be damaged if you run it without refrigerant. Ac clutch solenoid is usually is not driven by relay, because an ac solenoid don't really take much current to to kick in, unless of course it is shorted. It would either be directly from the inside switch usually in series with the fan control or driven by a small transistor in a circuit, and the electronic circuit is driven by the ac controls inside. I think the problem with your ac is that it has no refrigerant thats why the compressor wont come on.
