A few days ago on my 2014 Tesla Model S P85 with 99,399 miles, the horn and voice command stopped working. Interestingly enough though, anytime I get into my car, the voice command is activated and I have to either cancel it or let it time out. Horn from the mobile app works fine. Also, resetting the instrument cluster with holding the Skip and Voice Command buttons work. So I’m wondering if this is just a bug in the software.
I tried hard resets and full factory reset, and after a few days same issue. So I decided, since I’m out of warranty, to see if I can fix it myself.
I searched around but didn’t see anyone with the same issue. However I found a few people who took the steering wheel cluster off. I powered off the car and unscrewed the two screws behind the steering wheel and unplugged the brown and yellow plugs. I checked the contacts and it all looks okay and brand new. I also unplugged the power and “data?” Plugs from both ends of the steering wheel cluster where the controls would sit. However I didn’t see anything for the horn. I saw the two plugs for the air bags which I did not touch, just pressed to make sure it’s secured.
After plugging everything back, it still doesn’t work. Not sure what else to check. Any ideas?
