cadillacjeff7777 Posted April 16, 2011 Report Share Posted April 16, 2011 Can someone assist me real quick on where the horns are on the 08 DTS? Were they in the drivers fender behind the plastic in the wheel well? 2008 DTS Link to comment Share on other sites More sharing options...
cadillacjeff7777 Posted April 16, 2011 Author Report Share Posted April 16, 2011 The better question would be, where is the horn relay? 2008 DTS Link to comment Share on other sites More sharing options...
Texas Jim Posted April 16, 2011 Report Share Posted April 16, 2011 The better question would be, where is the horn relay? Not completely sure, it may be under the back seat... Let me find my manual and I will look... Link to comment Share on other sites More sharing options...
cadillacjeff7777 Posted April 16, 2011 Author Report Share Posted April 16, 2011 Well, it's not in my 08 manual. I found the horns behind the bumper cover on the drivers side. I unplugged so that I could search out the relay by listening while wife pushed horn on and off. It is in the vicinity of the under hood fuse/relay box on the passenger side. IT IS NOT IN THE RELAY BOX LIKE LOGIC WOULD TELL YOU. I can not locate it but the 15AMP fuse I have found to be post relay which I find odd. What if I spliced off of that circuit and out to a universal 30 amp relay. Any guesses on time delay between stock horns sounding and the added 4 sounding? I'd be curious as to any data on time it takes one of those relays to connect when 85 and 86 are powered. 2008 DTS Link to comment Share on other sites More sharing options...
Texas Jim Posted April 16, 2011 Report Share Posted April 16, 2011 jeff, I don't find a HORN RELAY listed at all... The HORN FUSE is F 17 in the underhood fuse block... I find it odd that there is no relay... Link to comment Share on other sites More sharing options...
