Window Controls Lock the Door?
Apparently randomly, my passenger window controls stopped controlling the passenger window. They started controlling the lock on the passenger door. Seriously. The window button now locks and unlocks the door.
Passenger side lock controls also actuates the door lock.
Driver side controls for the passenger window don't seem to do anything.
Anyone run into this before? Any ideas? Only info I found while searching were about sticky motors.
edit; this is a 2002 z06, low mileage.

Also, I did install a "C5 Corvette column lock bypass" from Corvette World Parts a few weeks previously.
Couple hundred miles of the passenger side window working between the two events.

It would seem that the passenger door module is your issue. It is in the door.
The driver side controls the passenger side via the serial bus and it interfaces only with the door module and not the door switch. Since the drive side can't control the passenger side it further indicates a module issue. This is the strangest door issue I have seen.
Pull your DIC codes and let's see if it shows anything first.
If you don't know how let us know. An auto store scanner can't do it.
In case you end up going into the door here is how to do it.

Unplug the passenger switch panel and see if the drivers side switch begins to operate the passenger door correctly. If yes, it's the switch and if no it's the passenger door module.
The door switch will do that if it gets moisture into it. I was working on my drivers door and left the car outside with the panel off and the switch connected and laying in the bottom of the door. It rained, water got in the switch panel and then the switch panel went all stupid. I dried it out and it started working fine again. I just kept running a heat gun for short bursts blowing the air into the connector area.

Your 02 should be the same as my 04. The commands from the drivers door go through the BCM and then to the passenger door module mounted inside the passenger door. If the signal does not get there, it is usually the door harness,it was on mine. I had a problem with the passenger window not working from either control,ie passenger control nor driver control. I took the harness apart on the passenger door and tightened the female sockets using the tip of a utility knife to squeeze each socket just a tiny bit so it would make good contact with the male pin. Do not over do it!
Cross talking as you seem to have is usually a wet or corroded connector but you should see that when you open the door connector at the hinge location.
I have the service manuals which always are a good investment for chasing these problems,once you have a direction to go. I can give you the connection drawings if you need them

Thanks for the ideas everyone.
Got the window working again. Turned out to be the common stuck motor problem.
Was poking around at it this morning and noticed when using the driver side controls I could hear a clicking noise from the passenger door. Gave the door a few good slams while hold it down. Unstuck it.
Now the passenger window control works properly too. No idea how or why it was controlling the lock while the motor was stuck. It's a mystery.
