Intermittent wiper failure

[Alana_Towers]

I am having this potentially deadly problem with my wipers working and not working in a most random fashion. I have checked the threads and I am wondering if i should change the GEM, and the switch etc. or.... has someone else come across this problem and solved it?
Please please please help

What year is your Taurus?

Can you describe what you mean by "...working and not working in a most random fashion?" Is this only when set on delay, or only when on low or high speed?

Have you checked some of the threads on the multi-function switch and wiper stalk? Sounds like this could be just dirty contacts in the wiper stalk, but it's hard to tell based on the description.

The wiper problems are seemingly random. One day they work just fine, the next they only work at one specific speed - no matter what the speed setting is. Other times they do not work at all. They do "park" properly, meaning they do not stop anywhere along the window. Some days I could have them set on fast and they go normal, then I try to set them on long delay and still they go the same speed.
Oh yes it is a '97 Taurus GL, 3.0L Vulcan

I would suspect the multifunction switch or wiper/turn signal stalk before the GEM module, unless you are having goofy problems with your door locks and other electronics.
