• This could be the fan switch itself or the blower motor. I suspect it to be the blower motor. Either the bushings or brushes in the motor may be defective. This will cause a load on the power and thus requires more power to get it to start. If th bushing are bad there may be a noticeable noise from the motor but not always the case. Also it may be possible to start it in the high position and then lower it to another position after it is running.
