Odyssey battery draining

50

Asked by Apr 29, 2015 at 04:48 PM about the 2007 Honda Odyssey Touring w/ Nav and DVD

Question type: Maintenance & Repair

My odyssey's battery keeps draining!  We just bought the van in November.  We thought
it might had a bad battery so we replaced it.  Worked fine until it sat for a couple days.
Battery is completely drained.  No interior lights were left on.  When the battery was
working the front interior lights are not working when the lights are set to turn on when
the doors are opened.  They won't cut on with that switch at all but the back lights do.  
They will cut on if you manually press them. The little orange light that lights up the
center console is not cutting on at all. We were thinking it might be a problem with those
lights. Anyway, it's not the alternater as its draining while it's parked and off as if
something on the inside was left on but we can't figure what. Any ideas how we can pin
point it?

I just read a post talking about the doors and the battery draining. We have been having trouble with the doors seeming to hang up when we try to open or close it. It would act as if something bumped it and would beep and open/close back. The safety feature and all...

In other words could the door be related and how and how would we fix it?

You appear to have a parasitic drain problem. I had this on a 2008 as well as a 2014 Honda Odyssey van. What the problem was is that a AC relay fuse had gone bad. When the fuse goes bad, it constantly tries to engage the air conditioning compressor even when the vehicle is turned off. As a result, it keeps trying to engage the compressor until the battery is totally drained. The AC relay, which is less than thirty bucks, should fix your problem. Swap it out with a new one, and see if that fixes your problem. If it does not, please take your van to a real mechanic to do an electrical system analysis.
