Battery Drain in Fuse W ASD/PCM
I have a 2003 Intrepid with a 3.5. Last winter and this winter I have a battery drain. I troubleshoot it to fuse W the ASD/PCM fuse. When I turn the intrepid off, after a couple of minutes there is still over 350 ma of current on the battery. When I remove fuse W, the ASD/PCM fuse, the current drops to less then 50 ma. I can re-install the fuse and the current does not go up to the 350 range. It stays at ~30. It did not happen at all over the summer but as soon as it got cold again, freezing temps, it started acting up. It may be just a coincidence, but I thought it was worth mentioning. I am unable to find a wiring diagram for this configuration but it would greatly help me troubleshoot the rest. Also, any ideas on why there is a current draw on this magnitude on this fuse. I am only assuming a short of some kind.
