Broken Locks and Windows (already fixed the infamous Black Wire)
My windows and locks do not operate, my back hatch is indefinitely locked and when I turn on my headlamps, the interior lights stay on (unless I turn the dimmer to off). However, the driver's side window and lock works as does the back passenger window (not lock) on the driver's side.
The window/lock problem happened about a year ago and after searching online I found the "black wire" problem and found it severed on both the driver and passenger side. Reattaching them fixed the problem. Fast forward a few months and it broke again.
Most Recent Attempt to Fix:
I went back and soldered the wires together and enclosed them with electrical tape. (Since I didn't have the proper tools the first time it broke, I had just hooked the wires together. Not pretty, but it worked at the time). That didn't work. So my dad and I had both door panels off to make sure there were no wiring faults inside the door. Again, nothing out of place and it appeared that power was going to the driver and passenger control panels. I would like to point out that the interior light problem cropped up after we attempted looking for the problem.
What the hell do I do next to try and A) fix my problem or B) figure out where my problem is? I have access to a multimeter and soldering equipment. I just don't know where to go next.
Thanks for any and all help!
