Any hope finding it? Brought to shop a year ago, replaced instrument cluster as recommended, appeared ok for a few months. There is definitely a parasitic drain but can't locate it.

 

Something often overlooked and that is the rear wiper motor, make sure it isn't stuck and can't return to the park position.

If you have some knowledge on how to use a multimeter,there are some nice videos on U Tube to help locating parasitic drains..
