For a temp fix, I slid some thin silicone fuel tubing (for model heli/aircraft) between the wheel and horn pad. Horn works fine, no more phantom horn blowing under braking. I have the new frame now but guess what? a year on I still have the temp fix in place.
yes they are just insulators, they prevent the horn contacts from contacting to ground. when the contacts touch ground the horn sounds. If the insulators are worn the horn sounds when the airbag moves around. Its really a simple concept. replace and away ya go.
Guys, forget about silicone tubing, bubble wrap or bushings or even a new frame. I tried to buy a new frame but of course the design was changed so it didn't fit my car without buying a new airbag. Go to the hardware store and buy a small tube of black RTV. Fill in the area where the bushings have gaps front and back and you'll be good to go after the RTV cures. Cheapest solution and fastest by far. To be honest the design is crap to start with so replacing the bushings or frame will only have the same problem in the end. Now the only way this fix works is if your bushings aren't completely destroyed with to begin with.
Tried rubber O-rings sized to fit the shoulder bolts. Didn't work.
Tried having Porsche dealer correct problem. Mechanic said part not available but to order grommet from TX parts purveyor. $75.+/- later that didn't work well either. Grommets must be installed from side they don't want to be installed from. (You'll understand when you get there.)
Eventually,,,,, 3 grommets went in from the back side and a folded piece of a business card (placed carefully to make completing circuit impossible at that corner and I've a three legged horn that works when asked to if I touch any of the correct three points. The End.
I followed Uicnic's directions today and for a grand total of $5 for T30 plus $8 for a tube of RTV silicone, I appear to have solved my horn problem on my 1995 993. This is one of the few DIY's I have done and it was super easy.
For those lazy folks, take a thin plastic card (hotel key card or something) fold in half, and insert in the seam on top of the horn between the horn and the wheel. This wedge keeps my horn functioning and does not require me to randomly gesture at innocents when braking to disguise the mechanical faults of an aging 993
Has anyone tried to use a rubber washer from the hardware store instead of the $24 grommets? I'm cheap
Yes, it works if the rubber grommets are damaged but still there. If it is gone completely, consider the "tube and business card" solutions as an alternative to a new grommets. I will try the RTV for a more permanent fix. I am tired of honking at strangers at every stop or speed bumpers! 😒
mine started a week into a new job and just after our first local all hands meeting. Got in the car after the meeting and drove through all of my new co-workers accidentally honking at them. I am sure there are many people who are still confused by my behavior
To fix this correctly cost under $100, so I can't understand why anyone is resorting to globs of adhesives and folded up business cards as a solution.
Yeah and I don’t get why people change their oil themselves...
The method I used cost less; it was less invasive; and it saved time because I didn’t have to wait for parts to ship to me. The airbag frame in 1995 models was a one-off so not risking damaging it in any way was a huge plus.
