'98 Olds.Cutlass, tilt wheel,3.1L, intermitent wipers, have repalced wind. washer bottle, motor and new delco pigtail(motor split, leaking), have no power to motor,(red wire), traced back to wiper switch-red still dead. Looking for wiring diagram-does power/ground come from wiper module or switch? My shop closed up-manuals inside.

Have the same problem. What did you find?

I have this problem also. I have a '95 Cierra but the system sems to be similar to a lot of GM vehicles. I put a meter on the plug at the motor/pump and when I turn on the switch I get no power. I have to assume the problem is in the switch (on the sterring wheel stalk) how much trouble to replace/repair that I wonder.....?
