The switch switches an electronic module based on the current delivered to it. In the switch there is a potentiometer (with variable resistance ofcourse) regulating the current. If the potentiometer is at a certain resistance the electronic module switches the main current to the spoiler like a relay.
The Original potentiometer is somewhat fragile and unprecise. Best is to switch between two resistors instead of using the potentiometer. If this is to much hassle you can use the potentiometer that is used in other thema's for the wiper interval regulation, it's the same part.
The spoiler goes to upward position if the electronic module is being switched through a 6,5K ohm resistor and to downward position if it is switched through a 1,3K ohm resistor

Perfect Stefan! Thanks a million!
One more small question, the electronic module, where is it?
Does that fail or is that unlikely?

It does sound like the switch is the most likely suspect!
Will talk to my mechanic friend today, and do some testing!

Thanks!
