2006 Mazda 6 Key fob automatic window problem

Is there a way to program how and when the automatic windows work? I dont know if the problem is in the key fob, wiring, or computer. The car has a feature that when you press the unlock button twice and hold on second press the front windows will roll down. For some reason sometimes the windows will roll down from one press and no hold. Also occasionally when i use the key in the door to roll up the window when I remove the key the doors will unlock and the windows will just roll back down. Is this a problem with the key fob, wiring, or computer? I know if i am sitting in the car with key in ignition but not on or anything sometimes i will hear the doors trying to lock or unlock every so often which im sure has something to do with the window rolling down problem. Im trying to avoid taking it to mazda to have it checked until i have an idea of what the cause is because they want to charge $100 just to connect it to the computer to look. Please help, any help is greatly appreciated.
