Blowing fuse

Post by ThisIsMikey »

My #12 fuse(25 amp) for the Interior lights keeps popping when I go to install a new one.
Any common reasons for this happening?

check both cigerette lighters espescially the rear one. You will actually have to unplug them to see if it is your issue. Was having same issue.

Well now that you mention it, my cigarette lighter looks like its been pushed in to the point where you can't grab it with your fingers.
I hope this fixes it! Thank you.

I'm a new owner as of 3 days ago. So I'll be on here fairly often. But even with the electrical problems I'm experiencing(Inevitable, from what I've seen so far) I absolutely love the car.

To get the cig lighter hot you push in the center section--the outer ring doesn't move.

YMMV :wink:

Now here's something. Do I have to remove the lighter or does just unplugging it work?
Cause I unplugged it, and it isn't popping the fuse anymore, but my accessories incorporated with that fuse still don't work.

That sounds like a sure fire way to hurt yourself and definitely blow the fuse if it isn't already. Don't short the plug.


The circuit will work fine without the cig lighter plugged in. Have you verified the new fuse it still good?

Last time I checked, it was fine. But I'll give it another look.

And in the mean time. I also have no turn signals at all, and no headlights. Just fog. And my highbeams only work on the intermittent switch.
It's a lot to throw out there, but these are my priorities before performance add-ons. And I'm anxious for those.

If the car has been sitting for any length of time, I would strongly suggest pulling every fuse and relay out of the fuse box and clean all the connections in the fuse box with jewelers file. Obviously disconnect battery before doing this. Then clean all the fuse and relay tabs as you stick them back in the fuse box. Sounds like you got a lot of oxidized, corroded or rusted connections. This is what I had to do to get everything working on my car after it was sitting outside for 2 years. Also check all plug connection in the engine bay, fenders, bumpers, etc..

Sounds like I have a patience testing time ahead of me. But I will get to it!
Thanks for all the advice. I'll be back if problems persist.

And that's a major Yes, on the corrosion part...

Just makesure you don't spread the prongs out further in the fuse box. If anything, try to close them up more so they are a tighter fit on the fuse tabs.
