Classic 900 Single-Stroke Wiper Modification
Although the wife's Hyundai Sonata is a nice enough little car, it is certainly no Saab -- but it does have a feature that I thought would be nice to have on my C900, a button on the end of the wiper stalk that gives a single stroke of the windshield wipers when pushed. It's perfect for those days when there is a light mist that accumulates on the windshield with random timing.
This is an easy modification to do. I used a Radio Shack submini pushbutton switch, RS part #275-1571. After removing the wiper switch/stalk assembly from the car, I drilled a hole in the plastic end just big enough to friction-fit the switch into place. (Though you could use a dab of cement if you like.) I then drilled a hole in the back of the plastic end piece for the wire to come out. Fortunately this piece is mostly hollow, you'll want to drill about halfway up the plastic to hit the hollow space.
Then it is a matter of fishing the wires through the holes and soldering them to the switch terminals, affixing the wires with wire ties to the stalk, and connecting them to the proper terminals on the Saab's wiper switch. (That would be terminals 53a and 31b.)
The following photos illustrate the procedure...
[assembling the parts]
Sorry for the out-of-focus shots, but I was using a borrowed digital camera and did not realize until later that it had a special mode for close-ups. This shows the hole drilled in the end of the wiper stalk, with the Radio Shack 275-1571 switch hanging on the end of the wires soldered to it. The wires are fished through the hole drilled in the back. (I used wires culled from a burned out "brick" power supply.)
[assembling switch]
Here is the assembled switch. Despite the poor focus you can see the switch friction-fit in the end of the stalk, the wiring exiting from the back, and the black wire ties holding the wiring in place on the metal stalk itself.
[electrical connections]
These are the switch connections you need to tie into, terminals 53a and 31b.
[installed in car]
Here it is installed back in the car. Works like a champ and doesn't look bad either!
DISCLAIMER: It is advised that the reader personally verify the accuracy of these instructions and the necessary wiring, and the suitability of this modification for his/her personal vehicle. This information is given on the basis of personal experience and it works for me -- I will not be responsible for any consquences which may arise from the use of this material on anyone else's vehicle(s)!
