Thank you for the reply. Your's is the second one I've received.
My experience leads me to believe Ford has a material and/or coating specification problem with this part. My intent with the posting was to see how wide spread the problem is. If I'm correct it would be hard to find this part in a junk yard that wasn't rusted.
I don't believe it's right for Ford to profit from their mistakes at the expence of others. When I worked in manufacturing, when we had a part that would fail outside the warrentee period but before the expected norm, we would redesign the part and offer it to the customers at cost. I don't know what Ford charges for this part, if you have to buy the whole assembly or just the verticle window channel.
To answer your question, both sides are rusted.
