Hi. It can also be the the motor. Or connections there are lose like ours. It's only few bolts and some plastic and the blower motor is out because it was totally rust. We got told around 400$ for a new. Got it out no rust. Just lose connection. If I was you. I would try take it out. Check it. It's in passenger sider.

But we still have problems it Will not run. So sometimes I need to move the connection. And then it's start.
I hope it would help. 1 time I do something like this.
