Is that a common problem on Prii? I couldn't find any threads about this. Is there a fuse that can be replaced or does one have to replace it?
Nope. Not common. I would check the fuse. I blew the cigarette lighter fuse in my Prius (I think, possibly my former Z) by using a crappy 12 volt splitter. I tried it again and it blew it again. Too bad I think it was too late to return it. My other splitters were/are fine and I've never blown the fuse again.
Thanks, that's exactly what I did as well. It seemed to work at first because the gps hooked up to it worked. I thought maybe it was running on the battery, but now that you mention it, it probably blew just after I hooked up the three in one splitter. The fuse must be in the front fuse box under the hood? I looked in there and couldn't see one, but maybe it's labeled under a different name or abbreviation. I'll look again....
