sticking horn button
Has anyone else had this problem with their 997 era 911? We've owned ours since new in 2012, don't blow the horn that much but even from new it seemed to stay on briefly after releasing the button which I mentioned to the dealer at every service visit but they never addressed it.
It got worse and worse and finally wouldn't stop, I had to pull over, locate and remove the correct fuse in order to quietly drive the car. This was about two years ago, dealer took forever to attempt a fix but did get it working correctly. Today it just did the same thing. Some goofball pulls up to a green light and just sits there so I blow the horn and it won't stop, same routine with fuse removal.
It is due for a service but if the dealer can't come up with a permanent fix it won't pass state inspection. Great car--silly problem but frustrating!
I did try searching this site but didn't see anything, I can't be the only one with this issue can I?

I’ve only heard this issue on Boxsters but check out the below thread, as it may offer some clues. On the Boxster, it was more related to the rubber grommets around the horn connections deteriorating causing the problem. On yours, I’m thinking it’s probably related to the placement of the airbag unit causing the problem, maybe having a wiring harness running against the horn connection. Check out the video below where the horn kept going off because he put the airbag in wrong, having a wire catching against something.

I had this happen to my 2012 C2S. The horn (pad) on the steering wheel began to stick after being pressed. Seemed it would do it after being unused for a week or so. I could lift the horn pad up with my fingernail to shut off the horn. Finally took it to the dealer for annual oil service and they were able to repair. Service Advisor said that it was a bad or broken spring. Easy fix and common problem. All good now. I think cost was 50 bucks or thereabouts.

Thanks, I had seen those posts from the UK, sounds strange they say it's a known problem but my dealer really struggled with getting it fixed a few years ago. I watched most of that video on replacing the wheel (that guy yaks too much!) but am wondering if I just shoot some silicone spray around the edges every once in a while if it would help? At least the video showed me the airbag was a contained unit so the silicone shouldn't mess anything up. Also didn't know there was a 997 Facebook page.
Any other thoughts appreciated.

No DIY advice from me but I will add that what you describe sounds exactly like what i went through. It continued to get worse and worse until finally the horn would not stop blowing at all. Very embarrassing. I'd have to find a place to pull over and pull the horn circuit fuse which thankfully is on a circuit by itself. The dealers first crack at fixing it took a while, this was before Covid, and only lasted about two years then it happened again. This time around the dealer staff was more competent, fixed it quickly and said they had used the wrong lubricant the first time. That was about two years ago and it still works as it should but I'm still very hesitant to use the horn.
Mine was new in 2012 and this started not long after we got the car and was noted and ignored on every trip to the dealership over the several years it took to get really bad.
I wish I could at least tell you what the fix was but I don't think squirting a little silicone lubricant in will help much. Good Luck.

I had this issue. There are two springs behind the airbag on the inside of the wheel. One spring was defective. The horn/airbag would stay pressed in and would not return to the normal position. We replaced the spring and it’s all good now.
Best wishes.

Simple fix - remove the module.
You'll see a plastic film on the contact surfaces, this may have reduced friction when new.
Remove this, reassemble. I may have added a small amount of silicone lubricant . . .

This worked for me - Thanks!
I checked springs (both OK), then did this film/tape removal followed by a dab of lithium grease on each of the four newly exposed surfaces. Sad that I avoided honking for a year when this solved it in five minutes.

My frustration with the horn is that it takes a great amount of pressure to honk. Is it possible to replace the springs with softer ones so that I don't have to pound on it to get it to work?

Before I dive in, any BTDT tips for popping the airbag out of the center of the wheel? Looks like a 4mm allen wrench does the trick and a decent amount of upwards pressure? With the battery disconnected of course.

Turn wheel 90 degrees
Turn the wheel to the right, then you can see the job and work while sitting on the door sill. I used a medium/narrow flat blade screwdriver. A thin prying tool helped to lift the airbag out of the hub.
