Electrical gremlin - Passenger interior door button
Need some help with an electrical issue. Left my windows down during a rainstorm like an idiot and now I'm having an issue where I can't open the passenger door from the inside unless I use the manual release in the floorboard. At first it was the window and door release switch. I bought both switches and replaced them. The window is now working but the door release is not. I checked the contacts, they look fine with no rust or corrosion on them. What else can I check to get this issue fixed? I've checked the fuse in the passenger floorboard, its not blown. The lock/unlock button on the door panel is working as well if that makes a difference. Is there a ground somewhere I need to check and clean? I am at a loss on what to do next.

Might still have moisture in the door panel that you can’t see or get at. I’d open it up, put a hair dryer in and let it run for several hours.... dry everything out. Sounds like everything else is working ok...
I had to replace the door latch on mine recently for the same issue. I first thought it was the switches, but turned out the door latch solenoid wasn't working properly. Bought one off Amazon and it fixed all my issues.
I have completed all the steps mentioned above. I removed the panels to allow for proper ventilation and to ensure all moisture dried out. Additionally, I replaced the door latch actuator. However, my passenger door still does not respond to the push button. The outside door pad functions perfectly, and the manual release cable operates as expected. What other components can I check to determine if there is a short circuit or a faulty connection?
If you do not have a scan tool to look at inputs and outputs for the door and you are unfamiliar with how to test a circuit as seen below find an auto electrical specialist in your area....you'll only be wasting your time and money...if it can't be opened from the inside it is NOT the actuator !!
Door Latch Inoperative from Interior Door Handle Switch
1. Ignition OFF, disconnect the harness connector at the appropriate interior door handle switch.
2. Verify that a test lamp illuminates between B+ and the ground circuit terminal A.
♦ If greater than the specified range, test the ground circuit for an open/high resistance.
3. Ignition ON, verify the scan tool Interior Door Handle Switch parameter is Inactive.
♦ If not the specified value, test the signal circuit terminal C for a short to ground. If the circuit tests normal, replace the appropriate door control module.
4. Verify the RCDLR scan tool Interior Door Handle Switch parameter is Inactive.
♦ If not the specified value, test the signal circuit terminal B for a short to ground. If the circuit tests normal, replace the remote control door lock receiver.
5. Install a 3A fused jumper wire between the signal circuit terminal C and ground terminal A. Verify the scan tool Interior Door Handle Switch parameter is Active.
♦ If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the door control module.
6. Install a 3A fused jumper wire between the signal circuit terminal B and ground terminal A. Verify the RCDLR scan tool Interior Door Handle Switch parameter is Active.
♦ If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the remote control door lock receiver.
7. If all circuits test normal, test or replace the interior door handle switch.
Have you tried to put a jumper wire (with an in line fuse) directly from a 12V source to the door opener button to see if it will work? Just a thought.....
If you've already replaced the interior switch and the latch, then my next guess would be that there is an electrical connector that goes to the interior switch somewhere that isn't making proper contact. It could be hidden behind the door panel. I'd have to consult the service manual to see for sure.

The passenger interior door latch switch passes through connector X666 (item 11 on drawing) inside the door panel. There is also a door control module (item 13) inside the door that could be a source of the problem.
You may also want to check and see if the lock/unlock indicator lamp (item 8) on the top of the door is working, and make sure the Park switch is working properly if you have an automatic transmission.
My guess is you're going to need to remove the door panel and start doing some troubleshooting.
Another clue may be the interior lights dimming function, since this switch also feeds that circuit. You might check that function and see if it's working properly.
