03 TJ Radio never turns off.

My 03' TJ got a little wet. Now the radio never turns off. Any Ideas?

I pulled the radio and checked the leads on the radio harness

Radio 12v red/white
Radio Ignition pink
to
Radio Ground black

And both had 12V with the keys removed from the ignition.

I used a volt meter to check the cigarette lighter ports just to see what else had power and they had 12V w/ the keys removed from the ignition.

Well you could wack it really hard and call it harsh names or check out your ignition switch to see if its letting power through. Was it everything that got wet or just the radio

You could wait til it dries out and see if the problem persists.

Did you pull the connector from the radio and look for water? If aftermarket pull the connector adapter too. Do you have any other keyed accessories? Are they working without the key too?

It was upside down in about two feet of water so quite a bit got wet but its been drying for about a week and half now.

I don't believe it to be an issue with the radio or its adapter, I pulled everything out back to the factory harness and that is where I checked the voltage on the:
12V - Red (which I believe should always read 12V)
12V Ignition - Pink (which always reads 12V but I believe should read 0 when the car is off and keys are removed)

I just pulled apart the steering column to look at the ignition switch, however I have no idea what I am looking at, or what needs to be disassembled to test and see if the ignition switch is what is letting the power through.

Ah well that sums it up pretty easy. Get a heat gun and start drying everything out completely. I would test the ignition wiring at the plug and if its showing voltage then focus your drying on the switch working it back and forth some. It may have shorted out internally

Pulled the plug from the ignition switch and radio remained on so the switch does not appear to be the issue. I pulled all of the relays in the fuse box under the hood and the radio remained on.
I believe it must be something between the ignition and the radio. Does anyone know where I can get a wiring diagram to trace the line from the radio backwards?

Id look at the speakers too bc if something is shorting out there it could cause a bad ground im assuming.

but I'm guessing that radio is finished...look on Craigslist for a used unit or you can get a basic unit at wal mart (Sony or pioneer) that will do most modern functions.
