Hey guys, I haven't noticed any 'electronics' sub-forum, so it was either here or newbie. Please move me as mod's see fit. Thanks.
Another problem with the 'central power locking system' but, this one hasn't been posted about (that my searches have returned). Yes Sir, I've read, re-read and worshipped my haynes manual/schematics(sp?) but to no avail--I still can't quite understand what's the matter. I have tested a couple things out though. Please bear with my explanations
How it happened:
My power locks ceased to work after a rather 'dumb' mistake involving a very quick
short circuit. At the time, the 10A fuse(engine bay fusebox) that resides in that 'yellow clip' blew. When I replaced it, my stereo, interior lights, etc. were fine, but no such luck with the power locks. With the kickpanel fuse(10A--PWR LCK) in, there are short intermittent and erratic beeps at very low volume. Only sometimes do I get a response from the door switch (lck/unlck). The response I get involves a loud singular beep (similar to chime when key is in acc, and you open door), and every-so-often a click from the area where your left knee belongs (2+ in down/left of steering column). There is no response from the passenger door though.
What I've done to try and figure it out:
I started by removing my center console/panels/radio/rear quarter panel to gain access to all the relays/main wire harness' that I should be concerned with. After a little exploring and setting off the factory alarm (which B.T.W. still arms itself and works properly), I decided to sever the brn/brn-white wires at each relay junction (rear quarter panel, behind stereo). As I clipped the first wire, my driver door unlocked. So I multimeter'd(new word =D) the brn/brn-white wires independently, using the steel around the steering column as a ground. Both wires are receiving 0.92-0.94V (I should have used a better ground but, it just shows there is + current flow through the wires). This is true at both relay locations. After doing this, I got around to thinking and tried jumping just one wire to complete the circuit, and continued this for both pairs of wire and both wires. Now, this is what confuses me. I've been told that our locking relays are negative triggered, but as the wires were jumped, the front relay locked/unlocked only the driver door, and the rear relay locked/unlocked only the passenger door--Just by jumping the wire. When I put the multimeter on the wire's supplying the .92V and moved the switch, the current dropped to zero and returned as I released.
Question:
Do these synopses(sp?) seem odd, or am I mis-understanding these wiring schematics?
What wire do I need to trigger to make both sides lock at the same time? and why wouldn't the negative pulses from the switch activate the relay?
Any help would be greatly appreciated. Thanks.

. Since I can not for the life of me find the fix to this problem, I just gotta cover all the bases.
