I appreciate the responses.

I lubed with WD40 and let it sit over night. Worked in the morning.

I am still a little confused about the nob on the motor. Looks like it should allow me to opperate manually but I can't turn it. I switched the radio on and ran to the back of the car to see how the antenna worked, the nob did not turn nor did I see anything moving but the antenna went up and down.

I think I'll pull the whole assembly out and once on my workbench I'll be able to really clean out and figure out.

Thanks again guys,
Joel
