Chevrolet Lacetti fuses and relays with block diagrams and descriptions

Fuses and relays are designed to protect power units and vehicle circuits from short circuits or overloads.

If any mechanism in the car stops working, first of all you need to check the fuses. Perhaps the problem lies there.

In the sedan, station wagon and hatchback versions, the fuse blocks are located in the same places. The connection diagram and arrangement of elements are identical.

Engine compartment

Finding the location under the hood is easy. It is located between the battery and the antifreeze reservoir of the engine cooling system.

To protect against water and dust, the fuses are covered with a plastic cover (black). The housing cover is secured with two latches. Dismantling is done by hand - you need to unclip the clamps.

It looks like this inside:

It is strictly forbidden to remove fuses by swinging them. This action may break the legs of the insert. For dismantling, tweezers or a flat clamp are used.

Interpretation of engine compartment fuses

According to the diagram, each fuse is responsible for a specific circuit, which allows minimizing the load on it. This also prevents the simultaneous failure of several vehicle circuits.

Decoding the engine compartment relay

Next to the fuses of the engine compartment module there are relays that are responsible for the operation of a number of electrical devices or mechanisms.

Salon

In the cabin, the fuses are located on the left side of the dashboard. To provide access to the fuse links, you must first remove the cover.

The cabin relays are located on a special bracket under the panel near the pedals. To gain free access to them, you need to remove the lower panel trim by first unscrewing two screws from the compartment for small items and removing the handle to open the hood.

Depending on the modification, the car may additionally contain a relay for climate control and forced head lighting.

Where are the Chevrolet Lacetti fuses located under the hood?

Under the hood of Chevrolet Lacetti cars, they are located on the right side near the battery, under a black cover. In the picture this block is o.

To access the fuses, you need to press a special latch:

The Lacetti does not start, the relay clicks, the starter does not turn

If the car does not start after the relay is activated, there may be several factors.

• The battery is dead. There is often not enough charge in the battery to move the starter armature.
• The motor windings are burnt out. If the thrower breaks down, it may need to be completely replaced.
• The contact of power supply lines has decreased. The damaged area must be descaled and repaired.
• There is no contact between the relay power terminals and the starter. Repair is carried out by replacing the relay or re-sealing the contact group.

The importance of the rear wiper

Because the rear wiper serves as a glass cleaner, which on all station wagon and hatchback vehicles gets clogged more than on sedans. It happened this way due to the close proximity to the road surface, the importance of this device is undeniable .

Removing and installing blocks

Before the procedure, you need to disconnect the battery.

Checking Chevrolet Lacetti fuses with a multimeter

Chevrolet Lacetti fuses have a transparent body; in most cases there is no need to use instruments to monitor them. It is enough to visually inspect the condition of the fuse element and it will be clear whether it is useful or blown.

Testing of car fuses with instruments is carried out only in cases where the case material or design features do not allow the performance to be determined “by eye”; the use of a tester or indicator will be required.

• Remove the fuse from its socket and lightly clean the contacts if necessary.
• Before checking the fuse with a tester, you must study the instructions for use. Connect both fuses according to the instructions on the device. When working with a tester, you must set the device to test resistance. If the fuse is good, the device will indicate a short circuit. If the indicator is used with a good fuse, the indicator will light up.
• A faulty fuse must be replaced with a new one. A prerequisite is that the technical characteristics of the new product must correspond to the recommended parameters.

If the device’s functionality has not been restored, then you need to look for other reasons for the failure. This may be an open circuit or a malfunction of the device itself. Further troubleshooting is much more difficult and is best carried out at specialized service stations. Unqualified intervention in the electrical system of a car can cause very unpleasant consequences.
