Horn Sounds With Moderate to Heavy Braking


Recommended Posts

Hey Guy's (and Gals) I've got a teaser for you.

Does any one have any experience with loose relays, shorts, or other electrical malfunctions that might be the root cause of my horn sounding when stepping on the brakes? So its not all the time, and it seems to be contingent on forward braking momentum;

- Light to normal braking the horn does not squeek or sound

- Moderate braking the horn will chirp, akin to brushing wires together to make an intermittent connection

- Heaving breaking, the horn just blasts.

I'm a little more aware about paying attention in traffic now...nothing more embarrasing that slowing down for a traffic light while surrounded by traffic in all lanes, and the horn blares. Gotta love tinted windows.

Any commentary would be appreciated!

I have a 993 with same issue. I have not been able to solve the problem as my car is a 1995 which has different steering wheel horn/airbag bracket than later cars. I learned this the hard way after ordering the repacement part from the dealership, disassembling the steering, and discovering the hange. Unforunately, the small rubber grommets are not available as a separate item, and the solutios I hve read online about fixing them by "reinforcing" with superglue did not work for me. If you come up with a solution please let me know as I am driving car with the horn fuse removed to avoid drawing a lot of unwanted attenton!!

I've successfully impletmented this solution...I used 8 #8 O-rings, and 8 3/8x7/8x.015 mylar washers (doubled up on the washers for the best "feel" on the horn). I left the OEM rubber grommets intact (did not cut them out). The solution worked fine. I think the horn may feel (push) just slightly softer than stock, but no more unwanted horn sounding when braking or backing up.

Not sure what the guts of your '95 look like, but there has to be a rework for the assembly as long as the steering wheel/horn mechanics are similar to the '96 vintage.
