Can you tell me how to know if a fuse is blown in the fuse box and if so can this cause the heat not to work?

Usually, the metal inside the plastic enclosure will have a U shape. If the fuse is blown, the curved part of the U will be missing, and the plastic will look a bit discolored/ or it will even be black depending on how hard of a load the fuse got before it burnt out.

You know your car has blown a fuse if whatever the fuse is for suddenly quits working. For example if your radio is playing and for no reason quits it may be a fuse has blown.

Tail lights are usually on the same fuse with interior lights and dash lights. That is so you will know when the fuse is blown. Brake lights are usually on a different circuit. If a fuse is blown, try to figure out the cause rather than just replacing the fuse.

Pull it out an look at it. Most of the time you can easily see it is blown. If not check it with an ohm meter.

Put a continuity check on it. This can be done with an ohm meter. If there is no reading then the fuse is open.

You can easily replace it but you need to know why it blew in the first place. All fuses are marked on the fuse box or in the drivers manual as to which circuit they protect. Determine which circuit that blown fuse protects and inspect that circuit for troubles.
