Default OBD II Port No Power Solution

I had a situation where my OBD II port under the drivers side dash had no power. My local mechanic couldn't figure it out so I called a local Chevy dealer for an appointmnet. I described the problem and she asked me if I had checked the cigarette lighter fuse? A little dumb founded, I said I would. Come to find out there was no cigarette lighter fuse. I must have used it replace another 15A fuse that had blown and didn't replace it because I don't use the cigarette lighter.

Would be nice if Chevy properly marked the fuse panel.

Just some information in case someone else runs into the same problem.

Sorry, I forgot to include the vehicle information

GM likes to bundle their fuse connections together... But that's good to know! I'll make sure to remember that one, lol

My '85 S10 had the park light system and the cigarette lighter on the same system (which when grounded to another ground in the dash, shorted the system whenever you plugged anything into the cig lighter, and blew out all my dash lights...)

I think you'll find more than one manufacturer that does this in their early OBD2 vehicles.

That's true, but I've only owned one OBD2 vehicle, lol... It's probably not just on their earlier ones... Most likely on all newer ones too... Why run more wires and take up fuse block space when you don't have to?

Yup whenever I hook up the old scan tool and have no power I check the cig lighter fuse. I do that however, after I check the lighter cocket first for loose change that would pop my new fuse. Korey

If everything on the car that draws current had it's own individual fuse, you would have a fuse box as big as the engine compartment.

It does say so in the owners manual. They can't list everything on the fuse panel or it would be way too big . God forbid they make the labels any smaller. I can't see them now LOL.

Well, not being knowlegable about the eletrical workings in my vehicle, I just found it amusing that such an important connection would be run by the cigarette lighter fuse. I fully understand that having a fuse for every light, switch, etc would be overkill but this one should have it's own. Great to see I can post such an amusing thread. Can't wait for the next problem to creep up. I'll be back if that happens!

Thank you very much.. This was causing me great pain over this weekend. I'm trying to locate a problem in the emission system and was just about to drive the truck to an automotive electrician to figure out why the obd2 plug was dead. You just saved me $100 diagnostic fee. Thanks again.
