If your both sides get +12 at the same time - most likely the original controler is bad. Should supply +12V on one and GND on other for a short time. If the both wires were shorted - your add- on would just fry.
In other message I explained how it works.
: My 533i and my moms 528e have both lost the power door locks.
: I have troubleshooted mine. And found that the power lines to the door locks are both getting +12 at the same time. My question is would this be indicative of the two wires melting together or maybe the door lock failure in such a way to make the two lines connect?
: I wanted to see if anyone had the same problem.
: BTW I have the keyless entry from JC Whitney so I can bypass the BMW door lock computer.
