OK, you have been very helpful. How do I determine if it is the switch or the wiper module?
There are 2 connectors the smaller one has the black, brown and purple wires. when this connector is disconnected the wipers do not work.
The other has yellow, red, orange, purple, green, blue, purple. When this connector is disconnected from the switch the wipers still run. Also, there is 12.75 v on the orange wire only. all others read zero. Please stick with me on this!!
I have enjoyed reading this expert's postings and I am providing the wiring diagram you requested as a courtesy to him. . I fully agree with his assessment of the situation.

When I remove the connector (blk.brn.prpl) the wipers stop. faulty switch?
What is the proper method to replace this switch?
first i would like to say im sorry i was unable to get back to you tomorrow i was busy with the family after work. but in order to remove the switch you will have to remove the air bag. there should be two bolt covers on the back of the steering wheel remove the two 8mm bolts from the steering wheel. ( note you should disconnect the battery for about 30 minutes this will discharge the air bags) then when that is removed you will see a 21mm nut (gold in color) remove this nut then you will have to jerk the steering wheel back and forth til it comes free. after that is remove you will have to disconnet the sir coil and the horn switch. finally you will see three holes like a triangle shape pattern remove these screws (same size as the steering wheel shroud). the wiper swicth is now removed. then reassemble the other way around. thanks again Jon
