Everybody sleep on it.  Thanks for all of the discussion.  It really gets the mind working.  I will post back tomorrow with status.

Draw a Diagram Please.

How it is hooked yp now.

You never mentioned 2 switches before

Maybe you ought to reconsider opening up the switch to modify it for separate pwr/gnd inputZzzzzzreverse polarity with a twist. - Page 4 -- posted image.

No need to open the switch we can deal with it.

I really think your last diagram is the best by far and I think dualsports idea to reconfigure the internals of the switch to have separate pwr/grd will be the way to go.  I will look at it in the morning and see how bad it would be.

I think I've got it going back to relays on the signal legs.  I will post back after I try it.  It seems too simple.

ok i dont completely understand what the heck is going on but to me it sounds like you have a switch that can throw both poss and negative up for pos down for neg or whatever but when you thro pos it feedbacks neg thru the line and vise versaumm i guess.
Have you tried reverse polarity on that signal wire.
meaning two relays on that one singal wire One for each switch with diodes. corespoding to the signal going to the relays
ok dont hate if i got your postings wrong and this was already discussed but i read and did not see it.
Switch
pos in
neg in
signal ( pos or neg)
take that signal wire and split it
relay 1
take one split and connect to pin 85 with a diode in order to make that a pos trigger relay. ( grey stripe facing away from relay)
take pin 87 make that your output to the valve.
pin 86 ground
pin 30 possitive 12 volts
87a not used
same for relay 2
take signal wire split connect it to pin 85 thru a diode with the strip facing the relay making this a negative trigger relay.,
pin 86 12 volt fused
pin 87 output to valve
pin 30 ground.
ok with the diodes and such in place the feedback should not be an issue becuase there is no way the valve can see that feeback since it is not connected the output wire of the valve does not see the input of relay unless it is supposed to .
Your main problem if it or this does not work is that the switch actually throws the opposite signal when you let go of it, Like if you push down you thro a negative signal., or whatever but when you let go of the down motion it automatically throws a possitive signal. if that is the case you cant use that as your switch and i would search for another factory looking switch.
hope this helps somewhat as i did not understand completely what your doing and such but post back,

Now I lost track of exactly what you want.

The way I understand it you want to control 2 valves with 2 switches and make both valves do what the switch tells it to do wheather it is on the right door panel or left door panel.
