Confused,
I noticed that you live in Michigan. I'm down here in Kentucky. 🙂 Just click on my name and send me an e-mail and I'll send a responce. I'm a regular here on the Pre-67 forum.
The answer to your question is NO there should not be a blower motor on a 1965 beetle that came directly from the VW factory. If there is one currently on the car then it must have been added sometime in the car's life. I'll give you additional information if you want it, just e-mail me.
Stick around here on THIS forum. There are a lot of really great VW people to chat with here.
Later,
Larry
Enjoy life to the fullest - in a VINTAGE VW
