Fuses
1. The main fuses are located in a block installed in the front passenger footwell. Ceramic fuses are used on early models; and on later ones - with flat fuse links. Additional fuses can be found in the wiring to some components. The car radio installed by Skoda dealers is protected by its own fuse, which is located in the holder on the car radio.
2. Access to the fuses can be gained by removing the cover from the brackets (photo).

3. Before removing a fuse, first turn off the circuit it protects (or ignition), and then remove the fuse from the socket. If the fuse is blown, the conductor in it will melt.
4. When replacing a fuse, always use a new one with the same current rating. Replace the fuse only after the fault that caused it to blow has been identified and corrected. The current rating is imprinted on the top of the fuse; please note that the fuses are also color coded.
5. If the fuse blows immediately after replacement, find the cause and fix the problem. If the fuse protects several circuits, try checking each circuit in turn (if possible).
6. If a spare fuse is used, always replace it immediately so that a spare of the same rating is available.

Fuse box - removal and installation
Removal
7. Disconnect the negative cable from the battery.
8. Remove the fuse cover.
9. Remove the two bolts securing the fuse box to the panel (photo), then lower the box to the floor.

10. Disconnect the connectors from the fuse box, carefully noting their location.
11. Unscrew the terminal nut and remove the power cable of the fuse box (photo). Remove the fuse box.

Installation
12. Install in the reverse order of removal; make sure the electrical wiring is connected and installed correctly.
Relay
13. In Specifications this Section provides complete information regarding the location and functions of the various relays; see also "Electrical connection diagrams".
14. Relay - an electrically controlled switch that is used for the following reasons:
- a) The relay can switch large currents over a distance, thus allowing the use of thin wiring and switch contacts.
- b) The relay can receive several input control signals, unlike a mechanical switch.
- c) The relay may have a "timer" function - for example, a windshield wiper relay.
15. If the relay controlled circuit or system does not work, the relay may be faulty, turn on the system; if the relay is functioning, you can hear a click when it is triggered. In this case, the components or wiring of the system are faulty. If the relay does not work, then either there is no supply or control voltage supplied to it. or the relay is defective. Checking the relay comes down to replacing it with a known good one, but be careful, since some relays can be identical both in appearance and in operation, while others look similar but perform different functions.
16. To replace the relay, disconnect the negative cable from the battery, then simply pull the old one out of its socket and insert the new one (photo). Finally, reconnect the battery.

Warning: The socket terminals can be easily damaged if the relay is installed carelessly.
Direction indicator and hazard warning flasher
17. The turn signal and hazard warning flasher can be accessed by removing the central switch panel (Chapter 12) (photo).

18. Before replacing a suspected faulty breaker, make sure the problem is not a burnt out bulb or a bad ground.
