Anyone else having an issue with battery drain because of instrument cluster.

After ignition is turned off, doors closed, I hear buzzing sound from inside the engine compartment (i think it is from DISA). Also hear clicking sound every 13 or 20 seconds. This sound (both clicking and buzzing) never stops.

If I physically disconnect the instrument cluster or remove the fuse for the cluster (fuse # 13), the noise stops after 2 minutes and the battery drain stops.

Here is the kicker: in addition to my original cluster, i've already tried 2 other clusters and the problem remained.

You have a parasitic draw somewhere in the instrument cluster circuit. Here's a really good thread on how to chase down the culprit:

Even when you lock your doors the car is still thinking and doesn't really go to sleep right away. I have tried the same thing, locked my doors while the car is off and i hear my cd/dvd drive still spinning and weird sounds coming from the dash. But the car will eventually go to sleep.
