Location of relays and fuses in the mounting block: 1, 2 – tweezers; K1 – relay for switching on the electric fan of the engine cooling system radiator; K2 – rear window heating relay; K3 – starter relay; K4 – additional relay (ignition relay); K5 – place for backup relay; K6 – windshield washer and wiper relay; K7 – high beam headlight relay; K8 – horn relay; K9 – alarm signal relay; K10, K11, K12 – places for backup relay; F1–F32 – fuses (circuits protected by pin-type fuses are listed in Table. 10.3)
Electrical equipment devices that consume a large current during operation are connected via relays that protect the switch contacts from burning out.
To replace relays and pin fuses, the mounting block is equipped with special plastic tweezers 1 and 2 (see photo).
1. Turn the three fuse and relay box cover locks 90°...
2. ...and, overcoming the resistance of the clamps, remove the cover.
3. Use tweezers to grasp the fuse and remove it from the connector.
4. Install a fuse of the same rating as the one removed into the contact connector.
Note: Small relays in the mounting block can also be removed with fuse tweezers. The remaining relays will have to be removed manually, since the design of the tweezers for the relay located in the mounting block provides for the presence of ribs on the side surfaces of the relay, but in this mounting block there are no such relays.
5. Install a relay of the same type as the one removed.
Note: Fuses of different ratings are painted in different colors. In addition, the fuse is marked with a numerical value of the current strength for which it is designed (nominal value).
