My Daughters Beetle is Over heating. When the idiot light comes on I popped the hood
and the cooling fans ARE NOT runing.
I did a quick electrical test on the fans
and the coupler according to the Haynes
repair manual. The Thermo control switch is
malfunctioning.
Before I replace it I want to make sure. The Fans should be running when the
engine runs Hot
What year NB? Gas or Diesel? VW had a run on bad temperature sensors. If that is it, the fix is easy and cheap. In your case it may be best to just replace the thermostat sensor.
There are other possibilities however and some are expensive. No matter how expensive they are, not correcting your current problem will be more expensive.

Where is the Temp sensor Located and can I Bypass it to eliminate it?
If the switch is not working why are you going on the internet to ask if you should replace it?
