The Model 3 is unlike any other car, in many respects.
Causing our customers a few headaches at the moment are the fuses, or, more accurately, the complete lack of fuses. Instead, the Model 3 uses virtual, or solid state fuses, that are not visible to the owner, essentially, they exist in a blackbox.
This means that when installing some of our electrical accessories, the Model 3 can act weird for a while, including things like:
- The door window dropping when changing bulbs
- some, or all ambient bulbs suddenly stop working
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, we've yet to determine an exact time frame (but feel free to comment here).
So if strange things do happen when installing the ultra-bright lights, or puddle lights, don't panic - just give things an hour or so to settle, and all should be well.
The ultimate fuse reset, according to a Tesla Tech, is to disconnect the 12v battery for a few seconds. This is not very convenient, and so far it's not been necessary for anyone to do that (that we know of).
We've not experienced any of these issues on our 3 (VIN 0047xx), but we do know that Tesla are tweaking things all the time in the production ramp, so one car is not indicative, but it's all we have to go on for now, we can't justify a whole fleet of them :-)
