Can I replace my BCM with a junkyard BCM?

Dealer wants $350.00 to $500.00 to exchange my BCM with a different one.
They tell me it also will need to be programmed after the install or it
will go into a fault mode and the van wont start. Is this true or can I
buy a junkyard BCM for my vehicle as long as it has the security feature
and plug it in? I'm trying to fix my random door lock/unlock problem.
Thanks.

 

On the older models you may get away with that, since you dont say what kind
of vehicle it is I couldnt answer that.
The newer models have so many options and all the modules communicate with
each other over the bus, I would stick with the dealer ordered part only

 

Tell me what vehicle and model year this is. I can likely tell you
exactly what you need to know.

2000 Town and Country Limited with security. VIN 1C4GP64L7YB713849. Doors
lock and unlock by themselves whether the van is running or not, moving or
not. I tried pulling the 40 amp "door lock/seat" fuse under the hood to
keep it from happening until I can figure it out but the ABS and airbag
lights came on as well as the turn signals and blower fan wouldn't work.
Put the fuse back in and its ok except for the lock problem. Newer battery
and cleaned the terminals. IOD fuse was cocked in its socket so I pushed
that in tight but no luck. Can I pull that fuse to reset something? I
disconnected the battery and turned the ignition and headlights on for 5
minutes then reconnected the battery but still no luck. Thanks for the
help guys... Its looking expensive. Help!

 

Man, it sounds a lot like an intermittent ignition switch. My 96 grand
caravan once in awhile will give the ABS lamp, no power to windows,
gauges, etc. It happens every once in awhile at ramdom. At first, my
wife was the one to see it happen. Then I was with her once when it
happened. She then carefully watched the problem the next time it
occured, and rocking the ignition switch back and forth brought
everything back. Comically, we still havent fixed the problem, as it
is not frequent enough to be forced into repairing it. You should be
all right with a used BCM, as your van has theft system in it already.

Take it back to Champion Chry and have them monitor the Disarm swithces for
the alarm. That is normally what causes this phantom lock problem.
When you schedule the appointment dont forget to have them do the recall
on your heated seats

 

what is the year make and engine

 

max i just got a email from someone who took a pcm from a 96 grand cher. with
out a security system and used it in a 96 with a sec. system and the bcm changed
it over so know they get to buy a new pcm and bcm for jeep #1 $1000.00
is alot of money for test parts it's just going to worse

 

no you can not
the van will think that someone is stealing it and shut down the pcm and then
that will also need to be replaced
take it in it just might be a bad connection but you won't know until fault
codes are pulled from the bcm

 

It's a 2000 T&C Limited, 3.8. I may have gotten it fixed. I cleaned the
contacts on the 3 door lock relays and unplugged then reconnected the
electric switch for the rear hatch lock cylinder. See my new post titled
"random door lock/unlock problem fixed... i hope". Thanks guys.
