[DML] Re: Unsynchronized door locks

["Toby Peterson" <tobyp@xxxxxxxxxxxx>]

Rich - I would start by carefully and completely marching through 
the door lock adjustment procedure detailed in the shop manual 
(P:02:11).  See also service bulletin ST-10-8.81 in the "Tech Files" 
section.  It can be rather tedious, but it is the best place to get 
back to factory lock settings.  This procedure focuses on getting 
the door lock wiper switches (bell cranks) at the correct positions 
so that they offer proper feedback information to the door lock 
module.  Where the manual talks about moving the solenoids back and 
forth to position the bell cranks (if necessary), you can shift the 
position by moving the linkage rod on the actuator where it connects 
to the forward lock rod.  A couple of things to look for - the 
switches can get loose at the pivot point.  The bell crank rotates 
around on a rivet.  I had to carefully "redrive" my rivets to 
tighten the switches up so that they rotated smoothly and 
consistently.  The next thing to look for is seriously bent lock 
linkage rods.  If you have an excessive bend, the rod will flex too 
much, and not move the mechanism enough.  Make sure that you are 
getting very good and consistent electrical contact on the bell 
crank wiper switches.  Chris Almy wrote a great piece on 
troubleshooting the bell crank switch positions a while back on the 
DML.  I don't have the message number, but it was a very nice write-
up.  Let us know if you have any further questions on this.

you manipulate the key and/or the inner switches you can generate 
all sorts of patterns regarding which side locks/doesn't lock or 
unlock.

That much I've checked.
