97ES300ME Posted October 5, 2010 Share Posted October 5, 2010 Hello, The horn fuse on my 97 ES 300 keeps blowing; I replaced the horns thinking they had gone bad; it turns out it was only a blown fuse. The old horns sounded pretty ill, which is why I replaced them. I now have new horns that keep blowing the fuse if I blow the horn for more than 1 or 2 seconds. Any advice? Thanks, John Quote Link to comment Share on other sites More sharing options...
SKperformance Posted October 6, 2010 Share Posted October 6, 2010 Are they new OEM from the dealer or new to you from another car ? The horns are drawing too much current , either get new ones or a wiring harness and relay Quote Link to comment Share on other sites More sharing options...
