My '91 has power door locks and I'am having a problem with one of the

 motors...on the passenger side. It keeps unlocking...must be activated
from inside. As suggested by one listee, I remove the motor, cleaned all
connections and even opened the motor to clean it.I reinstalled it but
still does the same thing than before. Any ideas how much is a new p.d
lock motor (Part # 255 959 781) in the States ?

Also, could somebody look at the four (4) brass, spring loaded
connectors on the sliding door (like pins).  On my van, there are four
pins/ connectors but 3 wires only...(no red wire). Is it normal ? How
many wires do you have?  You can check by removing screws and gigled the
think out. Thank you.
