When replacing fuses, make sure that the value of the new fuse matches the value of the old fuse. Fuses designed for different amperages may look the same on the outside, so special attention should be paid to the marking. Every electrical circuit needs a different degree of protection. Make sure that the marking on the fuse body corresponds to the current strength for which the corresponding circuit is designed. If the replaced fuse blows immediately, the cause of the blown fuse should be identified and repaired first. In most cases, this cause is a short circuit in the electrical circuit caused by a break or damage to the wire insulation.
Fusible links
Protection of some electrical circuits is carried out by including fusible links in them. Inserts are typically used to protect non-fused circuits such as the ignition circuit.
Fuses are similar to fuses in that their failure (reflow) easily determined visually.
To replace the fuse, disconnect the negative cable from the battery. Remove the burnt insert and install a new one in its place. Before replacing an insert, be sure to try to determine the cause of the overload that caused the failure of the insert.
Circuit breakers (thermal relays)
Thermal relays protect components such as power windows, door locks and headlight adjustment (electrocorrectors). Some of the circuit breakers are installed in the mounting block. The return of thermal relays to their original state on some models is carried out automatically, i.e. when an overload occurs in the circuit, the thermal relay instantly opens, then, after cooling, returns to its original state. If the circuit does not return to working position, it should be checked immediately. The normal functioning of the thermal relay confirms the health of the circuit. Some of the breakers are equipped with push buttons for manual forced reset.
Replacing fuses
To prevent short circuits and overloads of consumers of electrical energy, individual circuits are protected by fuses. Camry vehicles use state of the art fuses, these fuses are blade type.
Before replacing a fuse, be sure to switch off the relevant consumer first.
Pry off the fuse box cover with a narrow screwdriver and remove it.
A blown fuse can be recognized by the melted metal strip. The location of the fuses is shown on the inside of the fuse box cover.
Remove the defective fuse with the plastic tweezers located in the cover of the fuse box.
Insert a new fuse of the same rating (current strength).
If a newly inserted fuse blows after a short time, check the corresponding electrical circuit.
Never replace the fuse with wire or similar aids, as this could cause serious damage to the vehicle's electrical system.
It is recommended that you always have a set of spare fuses of different ratings in your car. A suitable place is provided for their storage in the fuse box.
The fuse rating is printed on the back of the fuse box. In addition, the housing has an appropriate color, which can be used to determine the rated current.
Relay
Relays are used to supply electric current to some elements of the vehicle's electrical equipment. Failure of the relay to function properly leads to failure of the element it serves. If any of the relays is suspected to be defective, it must be removed and checked at a service station or a specialized car workshop. Replacing a failed relay is done as an assembly.
