Yesterday I noticed that the van had absolutely no power. No lights and would not crank at all when I tried starting. I replaced the battery and still nothing. I first noticed this when I tried unlocking the van with the remote and it would not unlock. I show 12.5 volts coming out and 12.5 volts from the main fuse box. I am guessing a relay or fuse? It is hard to check since all fuses look to be good.

It sounds like the maxi fuse # 22, 70 amp needs to be checked for power. Here is a guide to help you get started:

I have a 2006 Honda Odyssey, I ran it for 10 minutes while cleaning ice off windows, then got in driver's seat placed vehicle in drive went to drive away, car wouldn't move, wouldn't even accelerate, few lights popped up on dash. So I turned ignition off then back on. Now I'm met with no power, no flashers either... I'm stumped
