Sounds like you are due for further haunting…I don’t think its fixed…if the radio is now inop…and the issue seems to have abated…then that may have been it… The other issue was the door ajar…I believe there should be a light in the cabin associated with that…
IF you have PREMIUM sound…and the radio was having an on off issue…Don’t forget about the AMP in the rear of the vehicle…(premium sound again) If that Amp remained powered up because of a Radio fault, then there’s the issue…
Until your vehicle is as “complete” as you would normally like to have it…with all accessories in place and working…the issue remains to be seen methinks… I’d rather have everything working and not draining…and I think this was the entire purpose of trying to fix the vehicle…No?
