So after a 300 mile drive, I rolled into my destination and the heater fan was blowing at full tilt. Adjusting the fan speed on the heater controls or the steering wheel controls has no effect. Even if I power the heater off it keeps blowing on high.

Has anyone else had problems with this. The rest of the heater/AC functions as it should. Im not even sure where to start looking or how to troubleshoot.

Thanks

Is the fan control switch on the passenger side firewall under the hood? Or is the plug for the blower on the passenger side cab side of the firewall?
