Trying to diagnose some faulty door locks. Does anyone have a wiring diagram for a '99 LX? Need to know the functionality of each PIN on the master switch so I can check for continuity in the driver's door harness. Any help is much appreciated.

Believe they LX should be same as LC... Are you talking switch side or are you talking at the Junction Box?

Switch Side. From what I'm reading 98-02 LC and LX have different master switches. LX has all auto windows, LC only has auto drivers window.

Negative... I like traditional books. Digital can make things easier to search for but hard swiping through pages of stuff with dirty hands.

Want to thank everyone again for the quick help. With the diagram from @planomateo and following the current described in the door locking functionality, I was able to narrow my issue to the circuit on the D/L (U) Relay which activates the unlocking of all passenger doors and hatch (this is the middle brownish-red relay in the first picture). 12v on the relay proved it had failed. Di-section of the relay revealed carbon build up on the contacts. Picked up a replacement at the local parts store for $13. How the relay failed, I just don't know. Perhaps aging door lock motors creating resistance in the circuit? Plan to do a little write up on this to help others.
Also, I ordered the wiring diagram booklet @jLB suggested to use for my future amplifier replacement. This is a high quality color printed book. Should have purchased this 5 years ago...

Any chance I can get those diagrams?
