Have a 2009 nissan Versa and the heater blower fan quit working.Now nothing coming out. Nissan mechanic said it lost ground and to replace the Rheostat. Tried that but still nothing. Tested blower motor and it works if put ground wire to it. Where am I losing ground at??

Very cold here and have little ones to take to school. Any help is greatly appreciated.
Thanks
