Dash 12v Accessory Receptacle Not Working

I do not own a Prius . . . yet . . . but in the past, I have had the 12v power out stop working on both a Chrysler and a Honda. The problem both times was a (if everything else is working fine) blown fuse for that particular outlet. Give a look at your fuses. Both my cars had two separate fuse boxes; the main under the hood, and the utility one down by your left foot, usually on the lower part of the dash. If Prius has some other set up . . . I apologize in advance!
Hope this helps.

 

Another note while I am thinking about this; in the case of the Chrysler, the fuse blew when I plugged in a 300 W inverter that had a short in the connection wires; be careful to check -- if you have plugged something in -- that that item is working OK as well (no shorts).

 

Look at the PWR OUTLET and PWR OUTLET FR 15A fuses located in the fuse box under the instrument panel, driver's side. Note that these fuses are a special size and you may not be able to purchase the correct replacements at a discount auto parts store. If this is the case then you'll have to buy the fuses from a Toyota dealer parts dept.

Or could it be that the ignition needs to be on?

 

don't run inverters through the cigarette outlets... they simply can't handle any sort of power draw.


now... shorts are bad.. period... if you short out your cigarette adaptors, you blow fuses.. but i you're connected directly to the battery and get a small short.. the car turns off (even while in motion)... plus is drops the parking gear pin, and all sorts of other goodies depending on what you're doing... (but it won't blow fuses like that.. unless you have inline fuses for the amp)
