It covers how they work, common failures and a few troubleshooting tips. School is in session! The power door locks on Eurovans and Vanagons are exactly the same, and in fact use the same actuators. The system is purely electric, there is no vacuum used at all. The system does not have any kind of �gcentral control�h. It is a very simple, dumb system. The two front door lock actuators are �gmasters�h and the ones in the sliding door and rear hatch are �gslaves�h. The masters have four wires going to them: One each red (12 volts all the time), white (12 volts when unlocked), yellow (12 volts when locked), and brown (ground all the time). The slaves do not have the red wire. Inside the actuators there is a motor section and a switch section. LOCKING: When either one of the front doors is locked (button pushed down or key turned in door handle), the switch section in the actuator moves down and provides incoming power from the red wire to the to the yellow wire. The yellow wire circuit within the actuator also provides power to the motor within via a �glogic wheel�h also inside the actuator. The motor inside spins until the logic wheel cuts off power to the motor, and the actuator is now in the locked position. Power flows to all the other actuators through the yellow wire, to the logic wheels inside of each, thus running the motors in each until all are in the locked position. UNLOCKING: When either one of the front doors is unlocked (button pulled up or key turned in door handle), the switch section in the actuator moves up and provides incoming power from the red wire to the to the white wire. The white wire circuit within the actuator also provides power to the motor within via the logic wheel. The motor inside spins until the logic wheel cuts off power to the motor, and the actuator is now in the unlocked position. Power flows to all the other actuators through the white wire, to the logic wheels inside of each, thus running the motors in each until all are in the unlocked position. The most common failure on Vanagons is a broken wire in the driver�fs door jam conduit, or a corroded master actuator, or both. On Eurovans it usually just a corroded master actuator (wires don�ft break on Eurovans). Master actuators are mounted vertically and tend to collect water over time. Slave actuators are mounted horizontally and almost never fail. The most common failure mode on both Vanagons and Eurovans is that one of the master actuators is no good, and simply will not run the system when locked or unlocked. Another less common failure mode on Vanagons is where one of the front doors is locked, and the system goes into a ghostly lock-unlock-lock-unlock mode, over and over. In that case, there is usually a broken wire in the driver�fs door jam harness, AND a bad actuator in the passenger door. What is happening is that, when the passenger door is locked, the internal switch tells the internal motor in the passenger side actuator to go to lock position, which it does, and power is sent out of the yellow wire. However, power can�ft get to the driver�fs side actuator via the yellow wire because of a broken yellow wire, so the drivers door actuator, still in the unlocked position, is still sending power to the white wire. So, the passenger actuator tries to unlock but can�ft because it�fs corroded, so it stays locked and continues to send power out of the yellow wire. So, now both the yellow AND white wires have power, and the system goes poltergeist. You have to fix the broken wire(s) and replace the bad actuator(s). To troubleshoot, on Vanagons you first have to check for continuity on the wires running to the driver�fs door actuator. If you are sure the wires are good, or if it�fs a Eurovan, just get a new actuator and replace the one in the driver�fs door. If that does not fix it, take the one you just removed from the driver�fs door and put it in the passenger door. If that does not do it, you have two bad actuators and both have to be replaced.
