01 ASTRO rear hatch electrical issues

[tonkatracker]

Hey guys my wife Drives an 01 Astro with rear dutch doors and I am having some issues with it When I open the hatch the interior lights do not come on, also when I lock the doors with the inside button or the key all the doors lock except the hatch (even the rear door). I can unlock and lock the doors using the key on the hatch but it still leaves the hatch unlocked (locks/unlocks everything else though)

any Ideas?

There are three or four contacts you can see them when open the door clean them with sanding paper en spray contact spray on them.

I dont have any contacts on the rear hatch (ther are 2 on the sliding door but none on the rear hatch)
