HELP! Horn fuse costs and DIY - 986 Forum - The Community for Porsche Boxster & Cayman Owners

lejolierogue · 03-16-2009, 09:05 AM

Dear Enthusiast - the horn on my 99 boxster is out. It was going off on its own and I realize I have to replace the horn bracket (I believe it costs like $65 on PelicanParts). But I need some info about the locating the fuse and the cost of replacing it.

Please advise and thanks in advance.

the horn fuse is B3 - there is also a relay though...

You can get it for less at Suncoast:

It's really easy to change:
1. Disconnect battery
2. Remove 2 torx screws from the backside of the steering wheel (behind airbag)
3. unplug airbag and set aside.
4. Remove 4 small bolts holding on the retainer frame
5. Install new frame.
6. Reinstall airbag and screws
7. Re-connect battery
8. ENJOY!

Thanks so much for this information. I have a horn that works when I plug the fuse in it goes off constantly. Now I will order this part and replace the bracket. Looking forward to getting this done.

I guess that I also have to be concerned about disconnecting the battery and my radio codes as well. Correct?? Do you have to reprogram your radio once you hook the battery back up?

Depends on model year is the answer but in your case w/ a '97, yes you need to input the code for your radio after reconnecting the battery. Post '03 MY, Porsche uses the MOST fiber optic system which no longer required the radio code.

I am having the same issue where the horn works but it goes off constantly when I put the fuse in. If I push the front of the steering wheel the horn stops. Below Releese 78 mentions the retainer frame. I have the airbag off removed from the car. Where is the retainer frame located? I looked at the Suncoast web site linked below and I could not find the part that Releese 78 is referring to and part of the reason I cannot find the part because I am not totally sure what I am looking for. Thanks in advance for your help.
