Ford Repair: 92 taurus wiper issues, cold solders, windshield wiper

Question
I have a '92 Taurus LX wagon 3.8L with a major windshield wiper issues. Low setting works properly. Most intermittent settings either are a steady low wipe setting, or it just moves a little then stops wherever, then goes and stops. High setting makes the wipers stop right where they are. This fact is handy in that wash /spray "works" but the wipers won't stop after the three or four wipes like normal, at least until I shut off the car or switch to high. So I have to have great timing to switch it all the way to high when the wipers are down. This seems to short the motor or whatever so they stay put.  I've tried 2 switches /arms from a wrecker, both with no affect. I've heard, online, about cold solders on the circuit board inside the wiper control module being a fairly common problem with these cars. Any help would be greatly appreciated! Any idea where this module is, or any other things to try? I would assume the motor is good or I probably wouldn't have much if any operation, right?

Answer
cold solders on general motors boards are very common i can't say i have seen that many taurus issues-there is a bulletin from ford addressing this and looks like you will need a motor as their circuit is built in. i recommend a ford motor as there are more than one.


^    SYMPTOM # 1. If wiper blades go to the park position or stay in the rest position - replace the multi-function switch (wiper switch). Refer to parts list at the end of this article.

^    SYMPTOM # 2. If wiper blades stop movement anywhere in mid-wipe travel during Low, High or Interval modes - replace the wiper motor. Refer to parts list at the end of this article.

a.    If both symptoms are observed during the System Tests, replace both the multi-function switch and the wiper motor. Refer to parts list at the end of this article.

b.    If only one of the symptoms are observed after completing both the Cold and Warm system tests, replace the component which corresponds with the observed symptom.



this procedure above it straight from the ford bulletin-there is a delay module but that is probably not your problem

good luck
