Delco PT-254 5-way for right door (GM 12101862)Delco PT-546 6-way for left door (GM 12125634)Both OEM connectors are available from www.rockauto.com, et al.
Delco PT-185 10-way for driver's door - Suburban (GM 12101913)
Assuming the left window functions, there is an open in the wiring between the driver and passenger side switches or the driver side switch is faulty. If you unplug both switches and both window motors, you can use an ohmmeter to check continuity of the tan and dark blue/white wires from side-to-side. If the wires of like color have continuity, the switch is faulty. Otherwise, there is an open in the wire with no continuity. Avoid connecting your meter to any pink wires since they attach to 12-volt ignition and serious meter damage can result.
Here are the steps as I'm understanding them. Let me know if this is correct:1) Verify that the left window works2) Unplug both switches3) Unplug both window motors* Avoid connecting multi-meter to pink wire4) Check continuity between each end of the tan wire between the switches5) Check continuity between each end of the dark-blue/white wire wire between the switchesA) Question: should the battery be disconnected for this? B) Question: Is there a way to test the continuity without disconnecting the driver-side window motor? Everything is all put together on that side and getting the motor disconnected would take a lot of work. C) Question: What's the next step after testing? I've already replaced all of the parts. It seems re-wiring is inevitable. I mean, if there is continuity, then maybe the motor connector is bad. I can't think of anything else other than the wiring.

Are you saying you already replaced the driver's door switch?
In the mean time, you might enjoy how I'm keeping up my window. :-)
