Onto the switch..
I bought a single wire probe and tested the driver'* door switch at the harness connector'* cavities. The wire colors matched the above schematic posted by Tech II
, but they were not in the same configuration as the above schematic.
I probed BLK/WHT to RED/BLK (lock).. then BLK/WHT to ORN/BLK (unlock) - there was no continuity light either way and the actuator did not operate in either connection. Then, just to make sure my probe was ok, I used a small paper clip to jump the same connections.. still no actuator function in either jump.
Just to be sure, I repeated all the above, ignoring the wire colors. I followed the terminal positions indicated in the above schematic - C to D = Lock and C to E = Unlock ... still no actuator operation.
Looks like the next step is to look for a short or break in the harness feeding the driver'* door. I don't know how to proceed on that one yet. Hoping someone will lead me through it.
Thanks so far
