I don’t think so. I have looked over car never touch anything or install anything radio,amp, alarm . I’ll look at grounds clean them but dought it. Still won’t hurt to look. Might take 30 min of my time.I'm inclined to think it's a connector or loose wire/ground somewhere also.
Probably not going to be fun to track down.
The reality is that it would be easier to fix if it was plain old broken.
