Keep blowing the same fuse in my dash panel, no idea why...

Asked by Jehosaphet Aug 15, 2018 at 06:57 PM about the 1995 Isuzu Rodeo 4 Dr S V6 SUV

Question type: Maintenance & Repair

The #3 fuse, labelled "Room L" in the fusebox under the left side of the
dash?  The 10 watt fuse keeps blowing...I bough a 15 for it yesterday and
while it lasted a little longer, it ended up blowing too.
Its the fuse for my radio, interior lights and for the dinging sound you hear
when you've left your keys in the ignition.

I checked the grounding on the stereo and the one coming off the battery,
both look fine, but that's all I know how to do, I'm at an impasse here.  
Anyone else have this experience or know what to do?

When you replace fuses, if you don't have the same number, or amp, then you need to use a lower one, not a higher one or it will blow. Get as close as you can to the same amp without going over! Hope this helps.

No, I don't have any kind of a fuse for the roof, as far as I'm aware of. I've got a moonroof up there, but its not push-button or anything. It a 10 amp fuse, its the correct amperage for the slot but it blows while replacing it...even with the truck turned off and no keys in the ignition. I've never heard of going to a lower fuse, but I've got plenty of fuses left over from buying packs with only one of the one I need, so I'll give that a shot.

You must have a short somewhere, it could even be one of the components itself. A temporary solution until you can track it down is to get a 10 amp, auto resetting thermal switch. It looks similar to a fuse but is a tad larger and has a metal case, you snap the legs off to the desired length. It will only save you from having to keep replacing the fuse. The picture included is only for a physical reference, you should be able to grab one at most auto parts stores
