Power door lick not working with fob or manually

20

Asked by Guru9JF1PG May 15, 2023 at 10:49 AM about the 2018 GMC Acadia SLE-2 FWD

Question type: Maintenance & Repair

Recently changed battery and that Now the power
locks won't work either manually from the inside of the
car or using the car fob. I check the owner's manual
but there's nothing really labeled as door locks or
power door locks fuse. It's more about relays which i'm
not knowledgeable enough to determine which one is
which. Was wondering if somebody knows the fuse Or
relays that are in charge of the power locks. Thank you
in advance.

Did you use a memory saver tool before disconnecting main power? It plugs into the OBD 2 port. If not then you have corrupted the BCM programming, so now you have to take it to the dealer and have it re- flashed to get everything back. Runs a hundred bucks in my area, but appointment’s are backed way up.
