Does the regulator just quit or will it ruin a new motor if it's bad? I need to change the heater motor and I don't know if I need to change the regulator also. This could be an expensive repair. I remember hearing a slight squeek from the motor, then I lost the high fan, now the low fan has quit. Brrrrrr, it's cold out there so I need to fix it.

Thanks,

Craig
