You are correct but I think the timer is in the power circuit that controls both the interior lights and the radio. I will recheck my book when I get home this evening to see if I can find where it is located and where it is wired. I can see the common wiring on this diagram but it does not actually tell where the timer is located. The diagram just isn't clear enough for me to see. Obviously it is malfunctioning causing everything to turn on and off.
