I know this is an old thread and there are other threads on this subject. But this is the one I found in my search that I want to reply to.Also in 2002, the Ody had an interior lights timeout feature if a door was left open. IIRC batteries were drained because someone left a reading light switched on. The timeout would not turn off the light in this case. So it would run until the battery was dead.
One solution is to always turn the master interior light switch to off after a drive. Also, switch to LED lights as mentioned by wreckedGT. They run cooler and consume 1/10 the power, so the battery may still be alive when you return to the van.
I have to keep my master switch in the off position because mostly other people's kids will mess with the map lights during the day. And I don't notice them as they are normally on with the doors open and I don't look at them when the doors are shut. So our van has been dead 3 times now in 1 year because of this silly design flaw.
My 2001 Grand Am will cut power to the ENTIRE car after 15 mins if the key is not in the ignition. Which is great. My Grand Am has auto headlights so that is nice. But even if I turned them on manually, left map lights on, glove box open, truck open, etc. Anything. If the key is out, then power is shutoff to everything in 15 mins. So I have never had a dead battery on that car due to lights being left on.
So I am pretty shocked my 2003 Ody doesn't have this simply feature and no auto headlights. And no glove box light. lol.
It's pretty lame not having the master light switch left in the "door" position. So at night I have to turn that on manually and turn it off manually as my new habit to make sure we don't have dead van.
And yes, I should swap to LED lights no matter what.
Now, to leave an on-topic comment as well. Thank you so much for a great solid state design for the power doors. I had totally forgotten about the remote doors on my 2003 Ody, now that I am thinking of installing a 2 way remote start alarm that I have had sitting around for years. Guessing I won't be able to just keep using the stock remote for doors only. lol.
