but I can't see all this simple work and parts costs when a 2 second spray of WD40 fixes the problem.

I replaced my door switch this week. I tried the WD-40 trick, and went from having an intermittant problem to a constant one. I finally got fed up and bought the new switch for about $20 from Ford. After I installed it (took me about 30 mins) I was able to get the old switch working. But I had to soak it with brake cleaner to free it up, then hose it down with WD-40 to lube it again. Then I put it in the box for the new switch, and put it in my toolbox. That way I have a spare if my truck or one of the 2-3 friends with SuperDuties has this problem again.

Yes, it may not work for everyone as well as others, I did my early 99 very shortly after I got it, (Bought in July of 01) it worked flawlessly until I sold it September of 06, and still is working I think, (know the guy that bought it, he has not mentioned any problems yet) So,, guess you take the chance... if it does not work, then a new actuator is in order.
