While fiddling around with the inside panel and making sure connections were tight, I`ve come to realize that awhile back when I rewired the tailgate harnesses, I don`t think that I made a new ground wire. Around the same time, I remember losing power to the doorlocks(all)and that the passenger window (front) is the only one that works (from its switch).
Do these run on the same electrical circuit as the tailgate accessories? (they work)
Where do I hook up a ground wire?
The relays (door lock and window)were replaced. Often when the heat is on I can hear them click behind the dash fascia where they are mounted. Also cleaned the drivers door switches a couple of times,too.
I`m not knowledgeable when it comes to this type of stuff but would like to straighten out an old problem.
Any ideers? thanks for your input.

Been a while since I looked around carefully in the back hatch, but the only ground wires that come to mind are the short ground wires that attach the two sections of the hinge to each other. If those are broken, everything will still work, but it is never a good plan to conduct electricity through moving parts (hinges and latches) because if they are well greased, they don't conduct very well, and if they aren't, they conduct ok but the electrical flow makes them corrode.

I would not expect your locks or windows to rely on the ground in the rear hatch (though I've seen stranger things). All I can tell you on those other locks and switches is that you need to take a voltmeter or 12V test light and start at the hot side of the fuse and go all the way to the motor until you find the problem (making sure that the motor or lock actuator are grounded).

If you are unclear on how relays work and how to check them, we can run through that for you. Come to think of it, I wrote a long discussion on that a couple of months ago, either here or on the S-70 board.
