My '02 GLX is getting hot.
I recently replaced the timing belt (belt, pump, thermostat and coolant). The fans come on when the AC is on high.
I am going through the troubleshooting of the coolant problems (http://newbeetle.org/forums/2-0-liter-gas/52013-overheating-problem.html#post753256).

The document says to jumper the red and the red/white to start the fans followed by the red to red/yellow wires.
The fan control module (FCM) has two plugs. One has four wires and the other has 14. Which harness should be unplugged? The four wire harness has red, red/white and two fat red/black. The 14 wire has many including the red, red/white and red/black.

Also, removing the FCM is very easy from under the car. Blind removing the two 10MM bolts is much less time consuming than removing the battery and bracket.

Thanks for any information

Thanks for the updated images. My copy was black on black with random-ish specks of white.

I was able to unplug the wire. In order to get my hand in there, I unplugged the rear wire harnesses that leads to the fans. Now the fans run fast when ever I plug the harness back together. This happens regardless if the fan switch is plugged in or if the key is in the ignition.

Before the fans would not run after the key was removed even when the engine overheated.

Any ideas? I am hoping it is the switch.

Here is how the tests went:

Initial conditions: engine cold to the touch, no key

red to red/white: both fans run
red to red/yellow: no fans run

My previous testing was invalid because I unplugged the 4 wire connector to the FCM and the 4 wire fan power connector in order to make room for my hand. These two connectors can be reversed resulting in the both fans running fast without the key in the ignition.
