My battery is perfectly fine, however something is draining my batterry when it sits for a period of time. What part might I need to replace?

If that does not work to find your key off draw, the final stage unit is suspect. Part number 64-11-8-385-549 It is behind and to the left of the glove box. It will draw current if bad even with all the fuses pulled. If it's warm when you pull it out, you found the issue. Go to Realoem. Com for pricing.
