Do the rumble motors need to be connected for these to turn on?

Hello everyone, I’m about a month into my broken pro controller saga, and I didn’t know if the rumble motors needed to be connected or not for the controller to turn back on. There is little to no documentation online regarding the pro controller, so I guess you guys are my best resource. If they are required, I would need to buy a new set of them since I am not comfortable soldering on my other, working pro controller just to test this. I’m getting really frustrated trying to fix this thing with so little reference material to use and my lack of experience on its own, so I hope the people here can help
