The horn is intermittently sounding while driving or parked. When parked the keys are not in the ignition and engine is not running.
It started out with my key fob not unlocking my car. So I decided to unlock my car manually, doing so set off the alarm and had the lights blinking and horn going off. So I then decided to order a new fob with a new battery (even though mine was new). That didn't work, so I decided to call someone to come program my fob, thinking that was the issue. So they did. It worked for about 2 weeks. Then the fob didn't unlock my car, brand new fob, brand new battery. Back to square 1, unlocking it manually dealing with the horn issue. Then, 1 day got in my car, started it and pulled in the windshield wipers, the horn went off and would not stop even after shutting off the car. It continued to be an issue and the problem couldn't be resolved. So we pulled the fuse to my horn. Now I'm driving with no horn, a hazard. Issues continued, my car now not only will the alarm still go off with flashing lights now it's not starting, it's even acted up while driving with the engine having weird spasms and accelerating. Worried because I don't know what to expect with this vehicle. I have a brand new battery and even got it tested by mechanics and they said the battery was fine. My car has huge electrical issues and the airbags apparently don't work either. But I've pulled out fuses and it sometimes reboots the car and will start normal and work for maybe a few days before acting up again. Sometimes it won't even start and make a clicking sound as if it's the battery but then after many tries or sometimes a few it'll start. This has been going on for a bit now and has just gotten worse and more worrisome.
This issue is well-documented online. My 2005 Jeep Grand Cherokee's steering column horn circuitry fails in the engaged position, causing the vehicle's horn to sound without driver intent. This is a safety hazard that can distract other drivers or cause them drivers to take unnecessary evasive action.
