door actuator

First, sorry I didn't mention it but we answer this type of question so often we often forget.  On a 5 wire actuator (or solenoid or dor motor, they all mean the same) 2 of those wires are motor wires, on yours blue neg sitting goes pos to open, green neg sitting goes pos to close. The other 3, black to ground (actually on some cars e.g. Ren 5 this is pos but it's irrelevant) and white and brown are the switches. Inside a 5 wire are positional micro switches. When that motor is pulled or pushed either white or brown will then STAY common to the black...that's why the "proper" relays shut down their coils after about 1.5 secs. When you have cheap i.e. non MES motors, if one motor is sitting fractionally (can be less than 1/4"-6.4mm) lower or higher than the other, it will affect the micro switch.

The answer to your last query is you are doing this wrong. Loosen the rod clamp, shut the door lock striker (so the mech thinks the door is closed), lock or unlock the door then align the motor so it's at MAXIMUM pull less about 1/4". Tighten. Remember my above coments, now it should pull sufficient to lock or unlock and control the passenger motor.
