Hello,
Sounds like a internally shorted fan speed controller. It is common for them to fail this way. On this car full power is always supplied to the fan and the fan speed controller controls the ground side. If it shorts to ground inside the fan runs continuously.
The fan speed controller is screwed to the evaporator down under the glove box. Good Luck, Bernie
