Clicking Noise From Rear Of Cabin

[bigalexus]

I recently bought a 2000 ES300, and really like the car. However, there is an occasional clicking noise coming from the rear of the cabin. What could be causing it? It's unpredictable and only lasts a few seconds at a time, so I haven't been able to pinpoint exactly where it's coming from. Maybe from the trunk. I wondered if it could be related to the stereo speakers or amp? I haven't taken it to the dealer yet. I haven't noticed any other problems, just the occasional noise.

Any suggestions?

Noises aren't always where they seem to be. Try taking everything out of the trunk, including the spare tire, test drive and see if the noise goes away.
