If you’ve noticed that the 12v outlet in your Tesla is no longer providing power, it could be due to a blown fuse. This can happen when cheaply made or older accessories are plugged into the 12v outlet and try to draw more power than the car can safely provide. Luckily, replacing a fuse is cheap and easy once you know where to find your fusebox.
Remove the access cover directly in front of the windshield. This can be done by pulling the four plastic clips hidden in the groove between the windshield and the cover towards you and upwards. The cover will lift out of place.
Open the fusebox on the left (number 2 in the photo below) by pressing in the tabs on either side and lifting off the cover.
There should be a diagram shown inside the fusebox cover. You’ll want to pull out fuse F35
You should be able to see a break in the wire through the plastic of the fuse. Now take your new fuse and insert it where the old one was.
Now would be a good time to check if the outlet is working inside the car.
If it’s back to working replace the fusebox cover by pressing down and snapping it back into place.
Slide the access cover back where it was and snap the four plastic tabs back by pressing them in place.
Teslas famously require little maintenance, but even they are not an exception when it comes to topping up your washer fluid. If you’ve received a “Windshield Washer Fluid Low” message on your dash, or notice very little fluid coming from the dispensers, the steps below will show how to add more washer fluid.
Open the hood (frunk) and locate the blue fluid receptacle on the right side near the windshield.
Open the cap and pour the washer fluid in using either the spout on the container, or a funnel.
Stop when the fluid level is visible just below the filler neck and replace the cap.
If you’ve noticed a “Key battery needs replacing” message on your dash don’t worry, your car battery is fine. What that means is that it’s time to replace the small battery inside the key fob. Luckily, it’s a simple fix and should only take a few minutes. The process is slightly different between the Model S and X fobs, so first we’ll go over the Model S.
If you’re having trouble opening the doors on your Model S, it may be the handles that are the problem. The handles present normally but pulling on them does nothing. The only way to open the door is with the interior handle.
If this sounds familiar you likely have a broken microswitch inside the door. Repeated opening and closing of the door can grind away at a wire inside, eventually severing the wire and causing the handle to no longer function correctly. Luckily, the problem can solved at home with no more than a new $5 microswitch.
The video below explains at length how to access the handle components and replace the faulty switch.
