I cannot get the windshield washer switch on the end of the combination
switch to work. Tested this down to a bad switch or wires. I took the switch
on the end off and checked for continuity and found NONE on the #10 wire.
The #11 wire is good because I can get the wiper motor to work in both
speeds. The pump motor is good because I tested it with 12 volts and it ran.
I am suspecting an open/broken wire due to 21 years of flexing.

AND while I had the car torn apart, I checked to see what was the matter
with the door locking system. Seems that the yellow with red tracer plastic
tubing that runs from the passenger (Right) front floor to the switch in the
door assembly had a crack where the tubing leaves the car and enters the
door. Looks like about 2 meters of this tubing and I will be back in full
service for the 1st time in the 6 years that I have owned the car. The
testing was way too easy. Started at the passengers side and split the
system. Found the problem in the door, but then had to isolate it to a bad
diaphragm or bad tubing. My mighty Mite Vacuum tester was the best
investment I've made in a long time...
