The video above shows how to replace blown fuses in the interior fuse box of your 1990 Nissan D21 in addition to the fuse panel diagram location. Electrical components such as your map light, radio, heated seats, high beams, power windows all have fuses and if they suddenly stop working, chances are you have a fuse that has blown out. If your D21 is experiencing electrical problems, you should always check the fuses first, because they are relatively easy to check and cheap to change. Some Nissans have multiple interior fuse boxes including in the trunk - the video above will show you where the interior fuse box of your 1990 D21 is located. If your D21 has many options like a sunroof, navigation, heated seats, etc, the more fuses it has. Some components may have multiple fuses, so make sure you check all of the fuses that are linked to the component in question.
If you need to replace a blown fuse in your D21, make sure you replace it with one that has the same amperage as the blown fuse. If checking and replacing the fuse for the component in question doesn't work, we recommend seeking assistance from a trusted professional mechanic. They should be able to figure out if the component needs to be replaced or if there is a short or some other problem with your D21.
Rotating the tires every 6,000 miles will improve your tire life by up to 20% and is fairly easy to do yourself. The video above shows you how to rotate the tires on your 1990 Nissan D21 without requiring any special tools. When you rotate the tires on your D21, check for unusual wear on the treads. If one side of the tire is more worn than the other, then you should have your wheels aligned by a professional. If the center of the tire has more wear, check your tire pressure as your tires are likely over-inflated. If both edges of your tires have more wear, your tires are likely underinflated.
While following the instructions provided in your D21's owners manual and in this video will help minimize the risk of injury. The best way to avoid injury is to never get under your vehicle while it is jacked up.
This video shows you how to change the oil and oil filter in your 1990 Nissan D21. When you change your own oil, you know that you are putting quality oil in your D21 and that the filter is being changed too. Most importantly, you get a chance to look around under your D21 for potential trouble spots. This video shows you the location of your oil drain plug, oil filter, oil fill cap and dipstick in addition to the steps needed to change the oil and filter in your D21. For most Nissans, you can wrap an old belt around the oil filter and unscrew it by hand. If you can't do this, see our page to find a Nissan D21 oil filter wrench. If your D21 is too low to the ground to access your drain plug and oil filter, be sure to use jack stands and safe jacking procedures before getting under your D21.
Most Nissans have the oil type printed on the oil cap - it will likely be 5W-20, 5W-30, 5W-40, 10W-30 or 10W-40. If it isn't printed on the oil cap, check your owners manual for the exact type before adding new oil. We recommend wearing safety glasses whenever you are working under your D21. You never know what could be dripping down from the engine, battery acid, engine coolant, brake fluid, etc. All of these fluids are extremely harmful to your eyes and skin so it is important to protect yourself.
The video above shows you how to replace the battery in your 1990 Nissan D21. We recommend changing the battery in Nissans every 4 years. Although some batteries last much longer, most batteries begin breaking down chemically after four years, so you could experience dimmer headlights and other negative effects before you have a dead battery in your D21 that you need to replace.
Replacing the battery in your D21 involves removing the terminals. When you reconnect the terminals, your radio presets are likely to be cleared out. In some D21s, you may need to re-enter a security code to get your radio to work again. Check for this code in your owners manual - it will usually be either a sticker or small card in the booklet. If you can't find it, call Nissan and they will give you the code for free. In many Nissans, the transmission "learns" how you drive over time and makes adjustments, so you may experience altered driving dynamics as your car re-learns your driving style after changing the battery.
