Car has battery drain. Already tried to pull fuses one at a time with volt meter or test light and could not isolate the circuit. It seems that the instrument cluster could be involved in the cause of the drain. Are there any common areas that are causes of battery drain on this model car? I have to re-ask this question as my original question got deleted or erased somehow.

Hello,

Hmm, I have seen the AC compressor control relay stick on and drain the battery in these cars. But, I would check the glove box light and the trunk light. The cluster does use fuse #18 in the driver side fuse panel which is hot all the time so if you remove this fuse the raw should stop if the cluster is the issue. Here is a great guide on how to find the draw and the most popular items to cause the draw.

Here is the location of the AC compressor clutch relay so you can remove it to see if the draw stops as well. Check out the images (below). Let us know how it goes
