What to do if your power window Fuse has blown?
Locate the numbered fuse that corresponds to the power window circuit, then pull out the fuse to see if the wire inside has burned through or is broken. If the fuse has blown, there is either a short or an overload in the power window circuit.
How can you tell when a fuse has been blown?
You might be wondering, then, how to tell if a fuse is blown–an actual fuse, that is. You will see that the fuse has melted, and there might be charring on the panel. A true fuse typically consists of a piece of metal, most commonly an encased wire, that actually melts when overheated. This is what stops the fault (aka “short” or “power surge” ).
Is it dangerous to replace a blown fuse?
Never replace a blown fuse with one of a higher amperage , which can be dangerous or can cause damage to your electrical panel wiring. You can take the blown fuse to a hardware or home store for help in getting an exact replacement.
What causes a circuit breaker to blow a fuse?
Any faulty wiring or connected parts risk a power fault (surge), which trips a circuit (or blows a fuse). So, again, the problem is not that the circuit breaker (or fuse) didn’t do its job but rather that there was faulty equipment.
What causes a Mercedes C class to blow a fuse?
In older cars, the power wire itself may work loose and chafe on the chassis. The wire insulation wears off, and the bare wire contacts the chassis, completing the short circuit back to the battery and blowing the fuse. Because the wire is loose, this short circuit can come and go.
What should I do if my fuse keeps blowing?
The process on overall is quite simple and it would be done within minutes. You would simply have to pull out the blown fuse and replace it with a new one. One thing you have to keep in mind is to replace the blown fuse with one having the same ampere rating. #1 Start by locating the fuse panel.
Why does my circuit breaker keep blowing fuses?
You likely already know where your main service panel is located and whether your system uses circuit breakers or fuses. And you probably also know that when all the lights and fixtures in a portion of the house go dark or dead at the same time, it’s because one of those circuit breakers has “tripped” or one of those fuses as blown.
Where are the fuses on a Mercedes Benz W204?
Testing fuses in place with a multimeter. Use the Mercedes fuse allocation chart to locate a specific fuse and amperage. For instance, the reading lamps are on fuse #17, rated at 30 amps and located in the under hood box. Figure 6. W204 fuse allocation chart (page 1). Figure 7. W204 fuse allocation chart (page 2). Figure 8.

Why is my power window not working properly?
If one power windows fails to move when you press the switch to lower it, the most likely causes would be a bad switch, a bad power window motor, a fault in the wiring circuit between the door switch and the door motor, or a wiring fault in the motor power or ground circuit.
What should I do if my window switch is not working?
If you are not getting power to the window switch, it may indicate a larger electrical issue that a qualified mechanic will need to inspect. Once you’ve located the source of the problem, follow the same steps to clean, lubricate, and replace the pieces you undid earlier.

What should I do if my power window won’t work?
Car repair experts recommend starting at the fuse box and checking voltage on the wiring at various points between the fuse box and power window, though this process can be tedious, and is often delegated to qualified repair shops. By far the most common power window mechanism, the regulator is also a very common point of failure in faulty windows.
