My understanding is that the cause is a failed door latch microswitch.
Leading evidence: 'failed door latch microswitch' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'failed door latch microswitch' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Replace three at different times and never experienced the symptoms' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I originally thought the window drop problem was a bad regulator, but further reading indicates a bad microswitch.

My passenger window is not dropping using either the inside or outside door handle.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My passenger window is not dropping using either the inside or outside door handle. My understanding is that the cause is a failed door latch microswitch. At the same time, the Central Locking LED is on all the time. If a door switch is bad, will that trigger the Central Locking LED? I can lock the car with the key remote. I originally thought the window drop problem was a bad regulator, but further reading indicates a bad microswitch. Is that correct? TIA
There are three micro switches involved in the window-drop function. It's unlikely that all three went bad at the same time. This sounds like a problem with the central locking system. The window isn't dropping because the car thinks it is locked.
Beats me. The system thinks that your passenger door is locked. Here is a breakdown of the door micro switches.
Switch for inner handle.
Switch for outer handle.
Switch in the latch that indicates whether the door is open or closed.
I have replaced all three at different times and never experienced the symptoms that you are showing.
On my car its the passenger lock mechanism that needed replace. There is a switch to tell if the door is open or closed and that switch failed. The way it works is when you pull the handle a signal is send to drop the window and another switch that indicate the door is open and hold the window down. Once the door is in closed position it send signal to send the window back up.
When the lock mechanism is broken, it tells the system the door is 'locked' not just closed hence your led light is on and it does not drop the window. When the door is locked, you pull the handle the first time to 'unlock' the second time to open the door/drop the window. It never get out of the 'locked' status hence window does not drop from either handles.
Try to hit the central lock button to unlock the door, you should hear the driver side unlock and the passenger side you can hear the motor but then the car double beep and the red light remain on the central lock button.
For more than a year, I sprayed some lubricant into the lock mechanism, I guess it frees up the micro switch and fixes the problem. Last month, I finally bought a used passenger door lock mechanism and replaced it.
