power antenna rattle

[ygu]

I am having a problem with my power antenna, when it goes up the motor continues to run and I hear a rattleing sound like the motor trying to push the antenna up and the teeth on the antenna rattleing. Has anyone run across this? Is it the mast or the motor? Thanks for your help

My power antenna only makes a grinding sound when it is supposed to go up or down. It stays up all the time now. I'd also be interested in knowing if there is a way to fix this.

mine only does it on the way up, the antenna extends, rattle, and then the motor stops. Going down is no problem
