Replacing the fuse insert with a higher value significantly increases the likelihood of damage to the vehicle’s electrical system. If you don’t know where the fuses are located in the Acura MDX (YD2) (2007-2013), carefully review this article, which details the location diagrams, ratings, and purpose of all vehicle electrical components.
Never replace a faulty fuse with anything other than a new one.
