How do you install a wiper switch on a 1992 Ford Taurus?

I once had a wiper problem with my 1992 Taurus and it turned out to be the wiper control module. There is a web site that tells you how to check the entire wiper system from the fuse block through the module, steering column switch and motor using a multimeter. I was able to trace my problem down and repair it using the instructions from this web page; I'm looking for it now but can't locate it.

The control module is a troublesome item on these cars though you may think it is the switch on the column lever. The module is located under the dash, close to the center and can be removed by simply sliding it from it's bracket and unplugging it from the wiring harness. It is a black plastic box about 4" X 4" and about 3" thick that contains mechanical relays and will make audible clicks when moving the wiper switch through it's settings. These modules were manufactured in Brazil (I believe) and many developed intermittent broken contacts due to what is called "cold solder joints". You can actually repair these modules rather than spend $65 to replace the part. Simply look at the circuit board for dark areas where there should be smooth solder joints and resolder them.

This was invauable information for me as I had tried a new motor and that didn't fix the problem. In checking the wiper module, which I found on the other side of my dashboard (in a F150 pickup), I immediately saw the cold solder joints. I reinstalled the module, but much to my dismay the wipers still didn't work. It turned out that the motor WAS bad and probably the reason the cold solder joint showed up (drawing more than normal current). Thanks to the guys above! - Pete
