crazy power door locks!

[sicK96GT]

I had a problem with my power locks on my door about a month ago, they wouldn't pop up when I used them inside the car or on the alarm. Randomly they started working again, but only for about 2 weeks. Now they are doing the same thing all over... Not opening the door on command, I must tell you I look really stupid when I press the alarm button, it beeps twice letting my know the alarm is disarmed then I have to open the door with my key.

Anyone had any problem like this, or know what it points to?

First thing I would do is make sure your batt terminals are clean and your grounds are good.

ive got some pretty substantial build up on my black battery terminal...blueish spongy build up...im guessing copper?

why would this happen and how do i fix it?

Get soem baking soda and water and pour on the terminals. What you have is acid rust. Don't handle the stuff and if you do wash your hands. A parts store with have a battery terminal treatment that will keep it from ding it again. Pick up a pack or 2

Get a wire brush, I would not be pouring water on my battery terminals.
