I notice my phone trying to connect to blue tooth in my car one night and I canceled it . It did it several times. Then my son tells me that my car is making a clicking noise. I went out to the garage and it sounded like it was coming from the passenger side like a relay clicking. I disconnected the battery and it stopped. Today I went out and connected the battery and the radio came on but no clicking and the key was still off. I started the car and the stereo works fine. When I turned the key off it all shut off. What could have caused this? How could the radio come on with the key off and what relay could have been clicking?
