Not sure is this is your problem or not....recently, my battery drained down. When I went to open the door, neither one would work. Luckily, I had the windows down and was able to get in the car. I charged the battery back up and was able to start the car but the neither door button worked. I reset the ECM and the door poppers now work again. These cars can do weird things when the voltage goes low.
Good Luck!
