heater fan

I have a 2000 beetle and the other day the heater fan stopped working . I was wondering if anyone has any idea of what the problem could be ??? Any help would be greatly appreciated

First check is the fuse but you probably have already. I've read on other forums where the fan controller mudule (under the battery) and the switches under the radio that turn it on/off can break. Also read where the motor just wore out. So unfortunately its a process of elimination. Good Luck.
