When i open my door after shutting the car off my radio, clock and interior lights turn off, but lately it stays on, it's not recognizing my engine is off so it stays on and my battery is dead the next morning! I tried removing the fuse for the night and the battery is still getting drained and wont start! what is the issue, anyone?
Re: battery keeps dying due to radio+clock staying on
You have a parasitic load(the device will stay on when car is off drains battery), take the negaitve battery cable off when you turn the car off will fix the problem temporarily, you have to take it into a qualified electrical mechanic and he can fix it for you.

Battery Rundown Protection/Inadvertent Power
In the event that any of the interior lamps supplied voltage by the inadvertent power relay and ground from the courtesy lamp relay were to remain on when the ignition is OFF after a period of 20 minutes, the BCM will deactivate the inadvertent power relay turning OFF all of the lamps on that circuit to prevent total battery discharge. Only when the ignition switch is cycled back to the RUN position will the BCM reset the internal timer and reactivate the inadvertent power relay. When the inadvertent power relay is not energized, the BCM utilizes the inadvertent power courtesy lamp supply voltage circuit to monitor for a courtesy lamp switch request signal. If a courtesy lamp switch is activated, the BCM will receive the signal to energize the inadvertent power relay by grounding the control circuit.
It maybe your radio !
U have a driver door defective courtesy light switch, this sytem has what is called delyed exit, it keeps all the accessories on until one of the door is opened, driver or passenger front will turn it off, so if the passenger front door shuts the radio off u need to replace the switch.
It sounds as if the pin on the lower back corner of the door opening is stuck in the closed position. It is surrounded by a little black rubber boot. If it does not freely push in with your finger and pop back out, the interior light won't operate when the door is open. This same switch also operates to cancel the parking lights when you leave the headlamp switch in the on position.
You may need to remove the door pin and lubricate it. Sometimes the plastic gets dirty and doesn't slide in and out freely.
is the door ajar light on sometimes also when driving? I had a similar problem with the light staying on. I determined that it was the passenger front door latch sticking. I opened the door, then took a screwdriver to push the latch shut on the door jamb. (Make the truck think the door is shut even though it is open). Then lubricate that jamb and pull the handle open to open the door. Keep doing this (closing with screwdriver and opening with handle) until the latch works freely. This took care of my light and door ajar problem.
