Sorry, I must've been drunk at that time.
Power lock system works this way:
- there is a motor in eevery door and a microswitch in driver, front passanger and trunk door units.
- there is a central controler (I think in driver side kick panel) which if it gets a signal from a microswitch that lock has been operatwd, it sets for about a second, +12V on one side of a motors and GND on the other (all + and all - sides of all motors are tight together) if you are closing and reverses polarity when opening.
- Driver side and trunk are master - control all doors to close and open front passanger doors can only open all doors. Rear units are only slave type.
- All added - remote operators simply tap into the two wires around the driver or trunk units and flip-flop the motor polarity.
- In your case, IF it is done that way and wires were shorted, you could't flip the polarities so wiring is probbably OK.
- I assume that you've checked the fuse.
- If you are skilled with voltmeter you can pipoint easy where the problem is.
Because of your controler probbably supplies its own power, I think it might just be the controler not sensing or not switching (in this case trunk an/or driver side are not oprating and passanger door doesn't open - try junk yard and repleace the control unit) or if trunk lock still warks - passanger side microswitch is bad (can't really be repaired - junk yard again)
Hope it helps.
