Recently I got a 09’ Police Impala and as usual they completely cut the entire wire harness under the dash on the passenger side. No audio, horn, nothing. I got the audio working and it’s been fine for month. I just got around to finding the tan wire for the horn and connected that. Everything works fine except when my left turn signal is on it pauses the radio?? Same thing when I apply the brakes. Doesn’t do it if I use my right turn signal. Also noticed that my left brake light will stay on for about a minute after I turn the car off. I’m convinced there’s some wires touching under the glove box because that’s the last thing I messed with before this started happening. I did nothing but connect the wire for the horn so I’m puzzled. I taped all the wires off that aren’t being used. I checked the fuses under the hood as well. I’m completely lost some body please lead me in the right direction.
