I had to use my wipers for the first time and they don't function properly. I found an old thread on how to test the motor and all checks out well, high, low and park using jumper wires at the wiper motor plug. When connected to the switch I have only low speed and off but no high or park. Looking at the back of the switch I see one spade connector that is not connected to anything. It is on the nine oclock position looking from the back. The spade in question is closest to the steering column. Is there a way to test the switch for proper operation and if necessary who do you use to rebuild/ repair it?
