Internal 12v Power Outlet Not Working

Internal 12v Power Outlet Not Working

2019 Tesla model 3

While using using g the internal 12v power outlet to inflate the tires it suddenly stopped working. I plug another device into the outlet but that did not work either. Both devices worked when I plugged them into a 12v outlet in a different vehicle. Had anyone else experienced this problem? If so does it have to go in to the service center to be repaired?

Circuit should have a circuit breaker, should reset on its own. Try your devices again but if they draw too much current they will just trip the breaker again. Try a lower current device like a phone charger with 12V socket adapter or such.

Blown fuse.

The fuses "self reset" like circuit breakers.

"The good news is that the fuses are self-resetting, which means that after the current on the circuit has settled, they'll normally reset themselves; this can take 60-90 minutes"

The same thing happened to me when I was using the Tesla tire kit. As M8B said, it's just a breaker that will reset on its own. I think mine took at least 30 minutes to reset.

Oh, thanks for the more detail M8B.

Is there a way to reset the breaker manually or using the touch screen?

1. In accordance with my username, would like to clarify some terminology: fuses are one and done, so these would have to be solid state circuit breakers, right?
2. the link 8 Ball gave also mentions disconnnecting the 12V batter to reset them instantly. In frunk, pry up on air cover to access.

Thank you all. It may have been the okder tire inflator I used that tripped the breaker. Fortunately I purchased a new one.

@3ngineer- to correct item 1, there is such a thing as a resettable fuse

Its good that Tesla chose resettable fuses to protect the circuits. Nobody wants to run to the auto parts store to buy a 20A fuse, or worse, stuff aluminum foil in the fuse slot just to complete the circuit!!!

The Tesla Tire Repair Kit compressor heats up and shuts itself down. It takes 20 minutes or so to cool down and reset. The 12 volt power in the car is most likely OK.
