I put up the checks below which I captured out of my .pdf you are using from the other thread. Also pics to help you locate components, and the aplicable wiring diagram. The connector is a three wire, red, red/yellow tracer, red/white tracer (ground). You need to re-read, I think your unplugging the harness (not harnesses) from the wrong component. You want the harness plug on the radiator fan thermal switch, not the fan control module.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
I hope this additional information helps. I'm going to start linking this thread to other posts. Please keep us all informed and let me know if you need something else, I'm going to start linking this thread to other posts. What is it exactly that you are trying to diagnose? You don't say.
