I am getting ready to rip into the passenger door and fix a problem with the
power door lock. Before I start, I want to run this by the brains of this
The problem I have is the door will not unlock, but does lock when the
button is pushed. During the lock/unlock selections, a loud "screeching"
sound comes from the door. Interesting, I have a neighbor with a Neon that
appears to have the same problem as I do, and a friend at work that has an
Intrepid with the same issue, so I am assuming this may be a chronic
problem, and if it is, I know someone reading this must have come across
this before. So, in my quest for making my repair time more efficient, I am
looking for experience readers to enlighten me what is broke. It sure would
make my repair time quicker as I can have the parts ready to go, and an
attack plan of exactly what I am going to replace.
See my posts in rec.autos.makers.chrysler between Jan 31 to Feb 4,
I have a 2000 300M, and initially my rear driver-side door couldn't be
unlocked or opened for a few days. Someone mentioned a child safety
lock may have inadvertently been engaged, but that was no the case.
It became operational on it's own a few days later, then one day
during it's normal auto-locking behavior it buzzed real loud and I
practically jumped out of my skin when it happened. Took it to a
dealer and got it replaced:

Called the dealer to make sure they had the part(s).
Old part is in the box (I asked for it).
Was asked if I had extended waranty (nope). I asked how much
that cost (when car was new) - he sez between $2k and $3k.
Cost of part: $139.70 ($105 USD)
Labor: $123 ($92 USD)
This is part # 04574023-AE
The latch and solenoid is one (compact) unit. 4-pin connector.
3 separate clevices for connecting 3 control rods (1 for lock
button, 1 for door handle, and the other for ???). Next time
I have a problem I'll take this old one apart and see what's
going on inside.
I definitely agree with MoPar man - the screeching is a dead giveaway
that it is a bad lock motor - common failure on the LH's, and it is
built into the latch. Remove door panel, unhook linkages and the small
electrical connector at the latch. The latch is held in by the three
large phillips flat-head screws that you see in the end of the door.

adddress with the letter 'x')
