Deedubbs Posted April 26, 2019 Share Posted April 26, 2019 (edited) I was putting an LED in my trunk and the bulb slipped, hit metal and blew a fuse, #9, and horn immediately stopped working. I also checked #24 and #9, both of those were fine. After replacing #9 interior domes and trunk lights work again, but still no horn. Any thoughts would be greatly apreciated, I feel unsafe driving without a horn. Edited April 26, 2019 by Deedubbs 0 Quote Link to comment Share on other sites More sharing options...
bangster Posted April 26, 2019 Share Posted April 26, 2019 Do you use your horn frequently enough to know it was working immediately before this happened then not immediately after? Sure I am using my horn more after being found 20% at fault for being hit by a red light runner, but I might use it once a week. I don't even double-lock my doors from the fob for the horn to sound unless I it is the daytime and I am not sure if I am in range or not. 0 Quote Link to comment Share on other sites More sharing options...
Deedubbs Posted April 27, 2019 Author Share Posted April 27, 2019 98% sure it happened concurrently. Thanks for the reply! 0 Quote Link to comment Share on other sites More sharing options...
drolds1 Posted April 27, 2019 Share Posted April 27, 2019 They're not on the same circuit. When you push the airbag, can you hear the relay clicking under the IP? 0 Quote Link to comment Share on other sites More sharing options...
bangster Posted April 27, 2019 Share Posted April 27, 2019 If you want to dive in and try bypassing the the SBJ with power to see if they work, or ground the wire to the SBJ that the steering wheel buttons (2 of them) should. possible failure points are the fuse, the clock spring, both buttons (at the same time? probably not), the horns (at the same time, probably not) or the relay or the "logic" in the SJB which would be a full replacement of the SJB unless you bypassed it with an external relay. make sure there is 12v on both sides of F24 make sure there is ground on pin 41 going to the SJB when pressing the horn button(s) make sure there is 12 to the horns when the button is pressed 1 Quote Link to comment Share on other sites More sharing options...
