So im having some trouble with my horn too and my srs light iss on. I went through this post and at first it seemed to be the relay. So i forked over the 40 bucks put it in and still nothing. I know the actual horn is good because i tested it and the fuse is good, relay is brand new. So it looks to me like its the srs/clockspring coil located behind the steering wheel. Has anyone taken the steering wheel off, do i need a puller? Also where do you guys go for part on the web? Any help is appricated.
