kurtflaitz Posted December 21, 2008 Report Share Posted December 21, 2008 My horn was not working when I got my car I looked in the fuse relay and noticed that the fuse was blown so I replaced the fuse and it worked for a day and now it is not working again. I told someone I know about it and he said to put a 20 in instead of a 15 and if it blows the fuse then I have big problems. Does that sound right to you guys? My heated seats are also not working I didnt check the fuse for those but could that also be a blow fuse? Link to comment Share on other sites More sharing options...

You do have a problem, the size of that problem is irrelevant. If I recall, the horn is on the same circuit as the AC clutch and cooling fans. If you AC clutch is bad you will blow that fuse. That fuse does not specifically say HORN does it? This is what happened when my AC Clutch windings melted, the AC clutch was shorted and blew a fuse that took out that circuit plus, the cooling fans, plus horn. Are your cooling fans and AC clutch working when that fuse is out?

JimD Posted December 21, 2008 Report Share Posted December 21, 2008 Your horns are located behind and below the right side headlamp. Get to them and unplug one horn at a time and you will learn which horn is causing the fuse to "fuse". Substituting a larger fuse will only cause more damage. And there are four fuses for the heated seat positions under the rear seat bottom cushion. They are identified as HDTST followed by LF or RF or LR or RR. All 10A. The most common cause of heated seat failure is a broken calrod element but the fuses must be checked. Jim Drive your car. Use your cell phone. CHOOSE ONE !
