THE "REVERSED" DOOR LOCK / BEEPER PROBLEM ...

  When using either the remote or the key in the door locking/unlocking. 

  You get a beep when the locks unlock, NO beep when the locks lock. 


There is a much easier way than taking out the rear seat to disconnect 
the battery, which wipes out all your settings and your radio codes, etc..  
Dan Hussey did a lot of hunting around in the wiring diagrams and
electrical TSB's... and found an easy solution.  He says:

With doors unlocked.  Open hood, open fuse panel under hood....  Look for
the relay that says "A1" on it.  It's a little metal one, and I can't
remember the exact location, but I think I'm right on the description.
Should be in the first slot on one of those rows, I think.  Anyways, pull
this relay and let it sit for a few minutes.  This disengages the alarm
portion only.  Put the relay back in and then lock the car with your key
(manually).  Wait a few seconds, then try the remote again.  Should be good
as new.
