Disconnect the negative battery cable from the battery. Place a test light between the terminal and cable. Make sure the key is off and door is closed. If the test light is on, you have a draw. Now you have to start pulling fuses one at a time and when the light goes out thats your draw. Make sure you hold the courtesy light switch in the door jam.

Good point...Clocks do have a draw but not enough to drain a battery unless its been sitting for a while. They will show up on the test light as a dim light. As strong draw will show up as a bright light.

If you pull the radio fuse before you start your testing, you'll have no confusion. Then use John's method of testing. If ther's no light, then the trouble has to be in the radio circuit, if there is a light, continue testing.

My first suspects would be the underhood light or glove box light, the switches to these often get knocked out of alignment.
