Fuse box diagrams (location, functions, purpose) in the passenger compartment and engine compartment of the Acura RDX (2007, 2008, 2009, 2010, 2011, 2012).
Checking and replacing fuses
If something electrical in your car stops working, first check the fuse. Use the chart or diagram on the fuse box cover to determine which fuse or fuses control the device. Check those fuses first, but check all fuses before deciding that a blown fuse is the cause. Replace the blown fuses and check to see if the device works.
- Turn the ignition key to the LOCK (0) position. Make sure the headlights and all other accessories are off.
- (Under Hood Fuse Box) Remove the cover from the fuse box.
- Check each of the large fuses in the underhood fuse box by looking through the side window at the wire inside. Remove the screws with a Phillips-head screwdriver.
- Check the smaller fuses in the underhood fuse boxes and all fuses in the interior fuse box by pulling each one out with the fuse puller located in the main underhood fuse box.
- Find the blown wire inside the fuse. If it is blown, replace it with a spare fuse of the same rating or lower. Spare fuses are located on the back of the fuse cover under the hood.
If you cannot drive the car without fixing the problem and you do not have a spare fuse, get a fuse of the same or lower rating from one of the other circuits. Make sure you can temporarily bypass that circuit (such as an outlet or radio). If you replace a blown fuse with a lower-rated spare fuse, it may blow again. This does not indicate anything. Replace the fuse with a fuse of the correct rating as soon as possible. - If a replacement fuse of the same rating blows in a short time, your vehicle likely has a serious electrical problem. Leave the blown fuse in that circuit and have your vehicle checked by a qualified technician.
Note
Replacing a fuse with a higher rating greatly increases the chances of damaging the electrical system. If you do not have a spare fuse with the correct rating for the circuit, install a fuse with a lower rating.
