there's a short in the wiring or in the fuse box
Hi if the fuse is to small it will blow or the light will not come on , if you use a bigger fuse you rum the chance of over heating the light switch and causing your wiring to melt.
Fuse 14 controls the remote central locking and windows - in addition it has a link to the interior lights. The most common fault causing the fuse to blow is the front centre dome lighing console. the cables melt and cause the fuses to blow. please see this link http://uk-mkivs.net/forums/p/340705/2307643.aspx
Fuses blow, in any application, when the current in the circuit exceeds the limit preset by the fuse selection. It is also possible, if the fuse terminals are corroded, for heat to be generated, causing the fuse to melt, giving the appearance of having blown.
Because then it wouldn't 'blow' at the prescribed amperage. -A fuse is made with very fine tolerance wire to melt at an EXACT amperage.
The fuses are made of either a solder/lead type mixture, or it's a thin wire, the thickness makes the fuses melt at a faster or slower rate when they get hot from a "short" or too much draw for the circuit. When a fuse "blows" is just a saying. But if you put a large enough "short" on a fuse it will seem to "blow" when it melts extremely fast.Also, to much resistance caused by dirty or loose connections on a standard plastic spade fuse can cause the plastic portion to melt.
In my case, when turning the lights on, the daytime lights turn off, but the taillamps still on. I found that the steering wheel combo switch (turning lights/windshield switch) connector (the clear color one, was excesive hot and the plastic melt. I changed the connector by a junkyard one and it worked. I guess if you don't have one handy, you'll need to fix your old one.
A fuse can blow when the electrical current flowing through it exceeds its rated capacity, causing the wire inside the fuse to heat up and melt. This typically occurs due to a short circuit, overload, or a fault in the electrical system. By breaking the circuit, the blown fuse helps prevent damage to electrical devices and reduces the risk of fire. Replacing the fuse is necessary to restore the circuit's functionality.
This is the amount of current that the wire in the fuse will "fuse" or open. and the Breaker will trip. Having said that, the time it takes to blow will depend on how close to the max the current is. If you put 13 amps on a 15 amp fuse, it will get hot enough to blow eventually. No fuse or breaker should have more than 80% load.
T means Slow blow , 6.3A is the maximum current this fuse will conduct , any more and the fuse will heat up and melt the conductor . Maximum voltage capacity is 250V , this means the maximum voltage that the fuse can block from "jumping" . It means you can use it in a system from 0 - 250V with a maximum current handle of 6.3A .
If a fuse fails to blow or a cut-off doesn't come into play, the insulation on the wires will melt and cause a short circuit.

A fuse, such as a fuse in a fuse panel, blows when the current flowing through it exceeds its rated capacity for a certain duration. This excess current causes the metal wire or element inside the fuse to heat up and melt, thereby interrupting the electrical circuit and preventing further flow of electricity. The blowing of the fuse serves as a safety mechanism to protect electrical devices and prevent potential hazards like overheating or fires. Fuses can blow due to overload, short circuits, or faulty equipment.
