I have a few questions about parts for my 1997 Sidekick (4 dr JX).

On the inside of my rear door (tailgate, whatever) there is an oval-shaped hole in the metal next to the plastic rectangular "main panel" below the window.  If I stick my finger in this hole, I can feel around and lock/unlock the door.  Is there supposed to be a switch or cover plate there?  Aside from a wrecking yard, does anybody have a source for this part? 

Above my rear window, there is a black plastic plug, and behind my spare tire, ther is a rubber plug.  Obviously these are for the rear window wiper.  On my wiper fluid reservoir, there is a spot where you could install a second pump, and there is an unused rubber tube coming out of the wire loom.  I'm assuming it would be easy to add a rear wiper, as the plumbing seems to be in place.  Is there already a wire harness behind the dashboard switch panel?  Would I have to run any wires or could I just pop in the switch and snap it in to a connector?

My multi-position cabin fan switch only works on the full-blast setting.  has anyone else had this problem?  Do I need to replace the entire panel, the switch itself, or is this generally fixable by cleaning some dirty contacts?

There is a piece of plastic trim on each side of the body, on the exterior, between the rear doors' windows and the windows that are mounted in the body (the ones that don't open, whatever you call those).  I need one of these pieces for the driver side.  Can't seem to find this online.

Thanx
