Hello Scotty,
I'm trying to locate the horn relay for a 2011 Buick Lacrosse CXL 3.6L VVT - 152700 Miles. When I press the lock button on my key fob, the lights flash but the horn does not sound. Pressing the horn button on the steering wheel, there is a delay before the horn will sound. Not 100% sure it is a relay, but that seems the be the place to start.
Thank you!
It should be located in your fuse panel, you have two, one under the dash and one in the engine bay.
Problem is there are a few relays listed as non serviceable. R18, your horn is one listed as none serviceable. From what I could research it should be underneath the engine compartment fuse box. Along with about 4 others.
Thank you! I saw the non-serviceable portion too; I'm going for the R18 based on this input.
there should be a setting in your DIC to turn on or off audible confirmation of remote lock.
Thank you. The option is already turned, so I was moving to the next stage of diag. I should have posted that I checked this first.
