I thought the motor was bad so I ordered one. But it did not seem to work.

Also, I took another switch from my friend and found out that the switch was good. Then probably the cable was bad? I am wondering how that works. It can only go up, not going down. Does that mean one cable controls the up direction, the other controls the down direction which is bad? How can I check that?
