Slider Power Door Lock

[CaptSquid]

Mechanically, the door lock for the slider on my 98 works just dandy. But, when using the power switch to lock/unlock the slider, it doesn't budge.

I think it may be something as simple as corroded door contacts, but I want to be able to address any and all options.

Any ideas?

Any time I had to mess with the slider locks it was the door contacts. Easy first step at least.
