How many parts are in a car? How many parts can possibly be defective?
Who in their right mind thinks that out of that many parts, that nothing will ever fail, or ever be defective?
Undoubtedly there have been countless numbers of defective cruise control master cylinder switches. Ford did not ask for defective switches, they did not order defective switches. No one lives in a perfect world. This issue is not about Ford, or Toyota, or any other car manufacturer. This is entirely about a parts manufacturer who made the switches for Ford, and Ford discovered the problem, which is their job.
Someone screwed up, the point is that Ford is responsible for it, but they did not intend for any switches to be bad. Their task is to make the vehicles safe. They are also trying to allay the hysterical responses of people who own vehicles with perfectly adequate switches.
All of the switches are not bad, all of the switches which are being recalled are not bad. Ford is expanding the recall just like every other business decision. They weigh the cost of doing only the bad switches or suspect switches, against the frivolous lawsuits which are undoubtedly are being filed by ignorant owners. Thus I bet a ton of money that the recalls are including a ton of other vehicles which have not shown to have any problems with the switches. They are doing some of that for political reasons, to appease those odd owners.
Find out if your vehicle is involved in the recalls, no official word is going to identify the critical switch models versus those less likely to leak. Let the dealership do their thing, make you happy.
Thanks Evan for the link showing the picture of what Ford installed on your truck. That is the exact harness which I was given, it is simply a fuse, as I said before. My truck did not require a new switch, back then the magic was the color of the top of the switch. That was before the last two recalls that everybody is worried about.
