WOW?????? Now do you people see what I put up with when I work on Cadillacs!!!!!!!!! Not sure if they actually said door panel but if there is an issue with the antenna in the door, it is part of the inner door switch asy & whatever switched you found online doesnt mean too much since you most likely searched people who throw parts at their cars & never fixed a car right with the first part ever. There are several switches inside that door, I would like to know them if possible, so far I only see 1 that actually controls the lock/unlock deal but if you think it is a loose wire or connection, be my guest since you narrowed it down to 2 & it is that easy
When you mentioned it to someone, did you actually have them look at it or did you ask the service advisor on the drive that most likely was just hired a few hours before you got there & didnt actually know they had electronic transmitters that automatically unlock/lock doors just by walking up to it or walking away.
There are a few test that should be done to confirm it isnt the transmitter itself, we have a lot of problems with them also
Just finished reading the rest of your post LOL!!!!!!!!!! Well you bought a Caddy, we didnt make the prices, we just pass them on to you!!!!!
But if that interior door latch asy cost that much, I guess you really didnt need that automatic locking/unlocking mechanism to work right anyway. Not sure he thought of you being a female that didnt know anything & also try to squeeze every penny out of you since bought a Caddy was not the issue either, I am betting you had an attitude & he just did what he could do to make you go away since we read people & we know when someone is going to actually want their car fixed versus someone who will complain about every cost of any part mentioned & most likely why they never got that part ordered because our dealership would have required you to prepay especially if you never been to our dealership & most likely you would have never returned anyway.
He may have been talking about that correct part inside the door panel & you blew it out of context, but any way. If you want it fixed right, then you need them to look at it to see what is the problem here.
I also like how these wanna-bes in these forums think they know it all. The bad thing is these newer Cadillacs are using more & more High Speed LAN & Low Speed LAN that do all the work now like that unlocking the door. Most Cadillac use more Serial Data communication to do its workloads.
The front doors do not have traditional door lock actuators. They have electronically controlled door latches that will operate depending on the status of the door lock system. This status is determined by the front door modules and the last known state of the lock system. If the last known state is LOCK, the latches will not release when the door handles are operated. If the last known state is UNLOCK, the latches will release when the door handles are operated. The front doors are also equipped with red door lock status indicators. The front door modules will supply power and ground to the indicators to illuminate them when the lock system is in a virtual state of lock. The indicators will not continuously illuminate when the vehicle is locked. They will illuminate for approximately 5 seconds after a lock switch activation or after a door handle has been operated and the front door modules are in a virtual state of lock.
