Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

If the switch itself, that changes to 'slow speed', has an internal defect, or if its contacts are dirtied, or if its connections are dirtied or broken, then you won't get a slow speed but will get a fast speed.

Since it isn't the fast speed that is defective, there is no question of the batteries or the power or the motor/motors either. It's basically something in the controls - and either the speed controller or the connections or the control/switch is most likely where the problem is, that needs correcting/replacing/repairing.

If this answers your question, please rate my answer. A five-star rating would be appreciated!
