I have experienced this with a Q7 fan blower. If the fuse is blown, replace the fuse with one that is exactly the same (see panel). The next thing you need is a good DVOM (digital volt ohmmeter), a 12-volt test light, some fused jumper wires and possibly a logic probe (for detecting digital signals in low-voltage circuits). If the battery is OK, your voltmeter should read within 0.4 volts (or less) of battery voltage at the circuit load point in any given circuit. Vehicle Engine Electrical Inspection Cost, The statements expressed above are only for informational purposes and should be independently verified. Cleaning your battery connections, especially if the terminals are corroded, will help ensure the battery lasts longer and performs well. 5) Broken Flasher Module.

The lesson here is simply to understand that a cursory visual inspection of a glass fuse such as this (or a BMV, or CCGX, or any number of other products that use glass fuses) is not always enough to determine whether or not the fuse is good; indeed, even a basic continuity test will not always reveal this condition, as -depending on how the filament melted- the fuse may present perfect or near-perfect continuity when tested with a multimeter. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. Due to the way fuses are engineered, the likelihood that a fuse would become faulty without blowing is pretty slim, but there are rare instances in which a fuse might appear completely fine, even though no current runs through it.
