We have a 2002 camry, and if you take the key out of the ignition, there is a clicking that comes from the fusebox under the hood. If you leave the key in the ignition it doesn't click. The clicking drains the battery. Also, if you take the key out, but leave the drivers door open, it won't click. Does anyone have a clue about what might be going on?

 

If you can, open the fuse box and determine which component is clicking. They should be labeled. Then post back.

Make sure the ign key switch is turning off. With key out check all electrical items that are normally off when the ign key is removed.
