You could possibly be losing voltage after the switch so I recommend checking the power at the fan # 344410TSDC36BNOKCY itself to ensure it's actually receiving 12v power. The switch could also be the issue since this component is what controls the fan's speed. It could be receiving a full 12v but not actually sending out a full 12v to the fan. The switch can be replaced with part # 344410TSSW12V.

I also recommend checking your ground as this is typically the cause of most electrical issues.
