door popper problem? lol

ok today after school i went to pop the driver door, and nothing happened. (my driver side always works, passenger side not always) so i walk close to the doors listening for noises, and when i press driver side button, the passenger side solenoid tries to pull, and when i press passenger side button, driver side popped open.. very weird, and annoying.. so im trying to figure out why.. anyone ever experience this before?
