GMC SUBURBAN WINDOW PROBLEM

1990 GMC Suburban • 168,000 miles

I am trying to determine (trouble shoot) a wiper problem so that I dont have to start replacing parts hoping to get the right one first. I no longer have window wash- I have removed wash motor and checked and it works fine. I no longer have intermittent wipe, and only one speed in stead of having High-Low speeds. Is the problem in the wiper motor itself or is it the switch in the column. Thanks

Check the white wire at the wiper motor if its shorted to the gray and purple wire at the connector going back to the module-

DO you mean check the white wire at the wiper motor to see if possibly it has shorted to the gray or purple wire?
