07 Edge rear wiper arm
 

Does anyone know how to remove the rear wiper arm of an 07 Ford Edge. I've removed the nut and the arm doesn't come off. I've tried penitraiting oil and a small grear puller it won't budge. Any ideas? Is it threaded on?

Should "pop" right off.

I had to use a puller...picked it up at advanced as auto cheap.

I had to replace our whole wiper arm/assembly/wiper because my wife turned on the wipers in freezing rain, and the pieces flew off. Anyway, I am due for a wiper change, and I know that there is a youtube video showing how to do it. I just can't find it at the moment.
