This is a 2002 Ford Mustang base model.
One of my headlights is stuck on high beams the other is on low. When I turn my high beams on both are high.
Not sure if this has anything to do with it but when I press down on my brake pedal my power dims a little.
Also, my ABS light is on and my traction control off button is on.
It’s never done these things before I put my new stereo head unit in.
