I have a 91’rx7 vert and somewhere in the setup of my horn something is wrong because it won’t sound off. When I directly connect power to the horn it sounds off so I ruled out it being the horn itself but somewhere in the wiring or something idk something’s messed up. Any ideas on what it could be whether the wiring or a fuse or a certain system I’m not making sure is okay?

Also, while driving on the highway, my wipers just stopped working in the rain. When I put the wipers on the car makes a humming noise as in the motor is running but no movement from wipers. Just happened yesterday so not too worried I’ll probably figure it out but just wondering if any opinions on that as well. Thank you 🙏

 

Hi I’m new to the group nice to meet u,

I’ve recently bought a 91’fc3s vert and the cars been pretty much fine. Car developed a consistent clunking noise coming from front section of car which after inspection turned out to be bad wheel bearings. After replacing them the sound was gone for a few months but eventually came back. Each time I replace the wheel bearings the sound goes away and then eventually comes back in a few months. I’ve tried ordering from multiple Mazda specialty part companies to confirm parts were not faulty.
Today I just replaced my third wheel bearing for the front left because the noise sounded very similar to how it was when the bearings went bad. When taking sharp left turns it makes the noise but when taking light turns, driving straight, and light or sharp right turns. No problems. Last owner did install coil overs into which I checked those components and made sure everything was tight there and also I went from 15’s to 17’s rims. I thought the size change could cause the problem but again the sound was fine with the 17’s for a while so I don’t believe that is the case. I’ve went and checked bushings and joints as well as replaced inner and outer tie rods with alignment.

I don’t know too much about these cars kinda learning as I go as well as learning how to be a better mechanic as well so any help or advice on what my issue could be would be very helpful. Thank you.
