Help with taz 3 blower fan

I have a taz 3 which iirc has the rambo1.3. The other day something happened and one of the fuses blew. I believe what happened was a fan wire shorted to ground. Now the little blower fan on the hex extruder will not turn off. Is the likely answer that a transistor on the board is fired due to the short? I apologize if this is covered somewhere because I am on my phone and cant read it very well. I searched the forum and didn’t see anything, not to say it isn’t there. Any help will be appreciated. Thanks, Greg.
