Horn no longer works with door lock or remote-start
Previously posted this as a horn-related issue, but now I have narrowed the issue down to the horn is no longer working whenever I lock the doors or when I activate the remote start. I have verified 1) the horn works from the steering wheel, 2) lights still flash when doors lock and when remote start is activated, 3) "horn with door lock" option in EVIC is turned on, and 4) turned this function off and then back on and still doesn't work.
Anyone have an idea of what is causing my issue or anything else to look at?
