I am new to the boards here. I have a 1993 Bonneville SE. It has a power antenna on it. This past winter there was ice build up on it and it could not extend all the way out. This happened a couple of times this winter. The antenna will not extend all the way out. Anyone have an idea as to what may be jammed? If anyone has a break down of the motor this would be greatly appreciated also. I plan on pulling the motor our but want to have a breakdown of the motor when I do this.

Thanks
