2018. Where is brake light fuse?
Generally speaking, it is rare for both bulbs to go at the same time, but they do! "Most" turn signal bulbs have two elements. Remove the bulb, (push in a bit, about a quarter turn and pull out) if there is two contacts on the bottom it is a multi bulb. You can generally see both of the elements in the bulb, and see if one is burned out. The short reason for this explanation is, you've said the signals are working! and "checking" the bulbs is the first "cheap" step. It also serves another purpose, you "playing" with them can help make them make "contact" if they were not seated correctly or if the contacts were dirty. If the bulbs look good, your signals should be a "bright light", and pressing the brake pedal, should make the same "bright light, and ... the four way flashers should make the same bright light! If you do not get the "bright light" or worse you get "uneven" light or "If" they don't flash, the next "in expensive fix" is to check the "flasher", the thing that makes the clicking sound when you use the turn signal or 4 ways. If all that is working, next turn on you park headlights. Do you get a "not so" bright light? You "should" at all the little lights around the car. If the light is backwards, bright instead of dim, there is a wiring problem and probably a short! If you don't then we start looking for fuses! And they can be anywhere in these new cars! The most usual spots are in front of the drivers seat up under the dash, below the steering column. Sometimes, up under on the passenger side. Sometime, under the front hood, one one or both sides, or all these places! My Toyota has four spots to look! The Smart car, up under the passenger side, waaay up under the passenger side! And then depending on the manufacturer, it can be one of several "types" of fuses. Generally speaking, a "good " ones you can see a flat wire through a "window" that connect between the two connectors. If the wire is melted or gone, it's a bad fuse! (With the most prevalent type they do not have to be removed to see them, at "fuse" tester comes in real handy, it has two prongs that touch inside two small holes on the top of the fuse to see if it has continuity, makes it really easy to check them all within minutes.) When replacing , get another of the same size (wattage) and replace, buy extra! If it "blows" again immediately, you have a more expensive issue, you most likely have a "short" which can be very difficult (and expensive) to find! Do not be tempted to just put a larger wattage fuse in, that can make the repair incredibly expensive! Good luck!
