Pre-emptive strike:
-Yes I know it's under warranty and to take it to the dealer
This truck has just over 2k miles on it. Starting today, the locks lock and unlock rapidly and continuously on their own. This starts when the unlock button is hit either on the door itself or from the key. Hitting lock stops this action, but as you can imagine it's then a pain to get in or out of the truck & also sets off the alarm.
I work with this truck and can't afford to leave it at the dealer just yet, but also will be driven insane if I have to listen to these locks do this for the next few days, not to mention running the batteries down (it does this whether the truck is running or not).
I know in previous GM trucks with lock gremlins, the most likely culprit has been a problem with a body control module. I see there are several fuses for the BCM in this truck. Any info on which, if any, fuse(s) are dedicated to the part of the BCM that controls lock actuators specifically? I can get by with using the key to lock/unlock for a few days, but I couldn't find in the manual which fuse is for locks.
The batteries have been disconnected so the ECU can reset, but that did not help. Nor did removing/replacing batteries in the remotes.
Thanks in advance for ANY advice. I'm sure this will require some warranty work, but as I said I can't be without it just yet and the dealer doesn't have any 3500s to loan.
