There are two fuses for the radio...RADIO No. 1 and RADIO no. 2
RADIO No 1 is under the hood in the engine compartment fuse box
RADIO no. 2 in in the fusebox under the dash, on the left side of the instrument panel.
The graciousness of a FixYa rating for my assistance would be greatly appreciated.
Try eliminating radio from power system by removing fuse behind radio or positive supple to radio. Replace backup fuse and check if drain still happens. If so, your radio may have internal power short and needs to be replaced.If not, shorts maybe along the the supply lines after the fuse.
Under the hood there is some. Not sure about your application, but it might control interior stuff too. It will be a bigger amperage than normally inside the car though
Soon as I have something concrete, will post here and email you direct.
Good luck and kind regards. Thank you for using FixYa.
The quickest way to find a short circuit is by putting a bulb in place of the fuse. Anytime the time the bulb lights there is a load. And if the load is a shorted wire the brightness of the bulb will give you a hint. So while you're at it, finding a 'short' is a quicky...keep your eyes on the bulb. gotcha!
your radio is staying on? you have a bad door switch.the bcm does not see door opening and thus does not turn radio off. most likely the drivers door.
