Need help with this issue! The car will unlock itself when driving and after I walk away, and the actual door locks work but i cannot unlock on either side (key fob works though). Please help!!
 
Cost to replace all 4? OR do you replace them as an individual basis?

Also to mention neither side door switches will unlock doors, only key fob can, so I'm thinking maybe the actual door switches? It wasn't an issue til I got my windows tinted and i believe water got in there....

I'm having the same problem!!! my car sitting unlock now smh. have you fixed the problem? i don't think its the door lock actuators, because I've done some research and it locks and unlocks with the fob, it just automatically unlocks by its self, so im leaning towards a short circuit somewhere or a faulty BCM.
 
Got a new window/lock switch (one thats on the drivers side that controls everything, going to pull it out and see if anything is burnt up, i have a feeling that when the windows were tinted they got water all over the switch (i noticed water on it when i left but didn't bother thinking it would have done this much damage). I'll let you know once i replace it.
 
Thank you so much let me know!!! My windows got tinted too but I believe what could have messed up mine is I remember snow got on it, a lot when I opened the door, I cleaned it off with my hand but u know how quick it could melt thru. Please let me know.
 
No luck, my door switches don't unlock the doors but the fob does and the button on the outside does. What could it be? Please help!
 
You're saying the driver side door switch don't unlock any doors? If so, would that's an indication the driver door lock switch controller is bad?
 
Any ideas what the issue is?

Just thought I'd post here, i fixed my problem just now!!! maybe it will fix yours too, just like you I've gotten rain and snow in there now and then. So I opened the door panel and disassembled the main door switch by separating the black plastic piece from the clear looking one with the circuits and right where the door lock/unlock switch makes contact is where the substance was. I cleaned both sides the button switch contact and the other contact on the clear plastic piece. I wasn't sure if the substance was some adhesive meant to be there or not, but i decided to clean it off with my flat head and some napkins, and tried it and guess what? i connected back and it worked like new!!! so i'm sure u have the same problem, but probably on the passenger switch? try it out get back to me.
I even called the dealer and they talked to me about 150 just to run a diagnostic, i went to different mechanics since I already bought the BCM (350 dollars piece for nothing!!!!) but they wouldn't install it because they didn't have the machine to program the keys which would need to be done if u put a new bcm in.
