    I'm guessing it is a blown fuse. Was using a tire inflator and it suddenly stopped working... anyone know how to replace this or where to get more info? Maybe covered by warranty?

    Blown fuse! Tyre inflator needs ~15A to work effectively, I think the ciggy-lighter is fused ~10A, I've found that running the inflator directly from jump-points under the hood, or from small 12V (7.5AH) gel-cell, or even from jump-starter pack to be far more effective! (…a nod is as good as a wink to a blind donkey!) Good luck!

    Fuses are NOT covered under warranty.
    Unless you already have a REAL good relationship with your dealer.

    See your owners manual for the location of fuses.
    Often there are spares right there nearby.

    Probably, especially if the tire inflator is rated at more than 120 watts (i.e., 10 amperes at 12 volts).
    See the section “Checking and Replacing Fuses,” starting on page 630 in the Owner’s Manual. The outlet in the center console box is fed from the P/OUTLET NO.1 fuse in the Instrument Panel Junction Block Assembly (“Left side instrument panel” in the Owner’s Manual), and the outlet for the rear seats is fed from the P/OUTLET NO.2 fuse in the Engine Room Junction Block No. 1 (“Engine compartment type B fuse box”).

    There is a chart on the underside of each fuse box cover that identifies the fuses, or you can find complete information in Toyota’s Electrical Wiring Diagram (EM32D0U), available by subscription to techinfo.toyota.com.

    Both P/OUTLET NO.1 and P/OUTLET NO.2 are 15-ampere fuses, Toyota part number 90080-82052 or 90982-09022. The originals are probably PEC’s BFLP series (data sheet and drawing), for which Littelfuse Low Profile MINI® 10.9 mm (0891015.NXWS) is a substitute, but neither of these parts is available in small quantities.

    I’d suggest buying one of the Toyota fuses; any dealer should have them. If that’s not an option, there is a similar Littelfuse part with a slightly smaller blade (10.0 mm), 0891015.NXS, available from electronics distributors. I’ve never tried these in the Yazaki fuse holders on a Prius, and I don’t know if the smaller blade size matters.

    You may see suggestions in other threads about using non-Low Profile blade fuses. These are more widely available and electrically compatible, but they are also too tall to reinstall the fuse box covers, so I don’t recommend this, except as a temporary fix.
    I doubt it; the warranty defines “Replacement of spark plugs and fuses” as maintenance and therefore excluded. As @Sam Spade suggests, some dealers might replace a fuse as a courtesy for a good customer.

    The single interior 12 Volt power outlet in my 2019 Prime stopped working. Only thing in it was an Anker power adapter to charge my phones. Figure it was a fuse, but find there is no Fuse at all in the Power Outlet 1 position listed on the fuse panel cover. Installing a fuse in that position makes no difference (Duh). I'm thinking the fuse panel cover is mislabeled and for another model, because I can't imagine it ever working without of fuse in place. I've uploaded pictures of the cover and the fusebox to show the reason for my confusion. According the diagram, there should be a 15 Amp fuse under the two 20's on the right. I found two blanks. Unless gremlins got into my car, pulled the fuse and put the cover back on, I have no explanation other that the cover is mislabeled.

    Anyone else run into this?

    The Electrical Wiring Diagram (more info)—updated, of course, since I wrote post #5 above two and a half years ago—now shows that all Prius Prime cars have at least one power outlet, with a 15 A fuse in the P/OUTLET NO.1 position. Cars built before May 2019 (i.e., model years 2017–2019) have a second outlet, as I described above. Some cars also have a USB charger socket, fed from a 7.5 A P/OUTLET NO.3 fuse in the Instrument Panel Junction Block Assembly,

    I can’t explain why your car has only one outlet, when the sales brochure for 2019 (PDF) says it should have two, nor why the P/OUTLET NO.1 fuse is missing. Perhaps the car was modified by the dealer or a previous owner.

    In any case, have you checked the P/OUTLET NO.2 fuse under the hood?
