You can check the operation of this unit by turning it on at maximum speed with the engine running. If everything is normal, then the noise will increase noticeably.
Otherwise, you need to quickly fix the breakdown. After all, driving in the winter with the stove turned off is not very pleasant. In addition, such trips are extremely unsafe; frozen glass significantly reduces visibility. Therefore, the sooner you fix the problem, the better. Everyone can replace the fan. It is enough to stock up on patience and tools.
Reasons for refusal
Replacing the fan and motor of the stove with a VAZ 2114 maybe not needed. The cause of the malfunction may be in other parts of the vehicle's heating system. Therefore, before changing the fan, be sure to check all the options for the problem:
- The failure could be caused by a blown fuse. The fuse F7 is responsible for the operation of the fan. It is designed for a current of 30 A. Also, a headlight washer motor, a glove compartment illumination, and a heated rear window are connected to it. If these systems fail at the same time, the problem is in the fuse. Remember to check all of these systems for shorts;
- Bad contact in the mounting block. Sometimes the contacts in the wiring block are oxidized, in which case it is enough to simply move it. This usually helps;
- Switch failure is a common problem. Check the functionality of this element.
Replacement
If you nevertheless come to the conclusion that the problem lies precisely in this element, then you will have to replace it. It is advisable to install a new fan. Used can quickly fail. And it is impractical to repair the deteriorated one. When replacing, you will have to do the following:
- Disconnect the battery. This will save you from a short circuit and failure of some of the electronic systems of the machine;
- The side heater cover is removed from the driver's side;
- Under the dashboard, you need to find and disconnect the positive wire going to the fan;
- Unscrew the lowest heater fastening nut. The negative wire of the motor is removed from the stud;
- The hood opens and the seal is removed. Unscrew both screws securing the fan casing;
- The casing is removable;
- Unscrew the screws securing the fan. There are only 2 of them, for this you need a Phillips screwdriver;
- Unscrew 5 screws securing the air inlet grilles. They are located in front of the windshield. Next, remove them;
- The fan rises slightly and is removed from the mounts by sliding it forward (towards yourself);
- The fan casing rotates 90 ° and can be removed;
- Before installing a new motor, thoroughly clean the compartment from the dirt accumulated there;
- The assembly is carried out upside-down.
Fan repair
Of course, a new fan is inexpensive, but it's still better to have it repaired. Inspect the case first. They are both collapsible and non-collapsible. The first ones have 2 screws on the ends. Unbreakable are assembled without them. In principle, both options can be repaired.
Let's start with the collapsible option:
- We remove the impeller. She will have to be shot down;
- Remove the cover by unscrewing the screws;
- We examine the brushes, in most cases the problem is in them;
- To replace them, you will need a soldering iron and a screwdriver. First, we unsolder the wires of the old brush, and unscrew the screw of its fastening.
- Do this carefully, do not lose the springs. Installing a new brush;
- Putting everything together in reverse order.
You shouldn't have any special problems with this work. It is much more difficult to restore a non-separable fan. But in general, if there is a desire, this can also be done. To do this, you need to squeeze out the 2 clips holding the lid. The complexity of the situation is that the ears of the clips break off easily. And if this happened, you still have to go to the store for a new fan. The rest of the steps are completely identical to repairing a collapsible engine.
Conclusion... As a rule, stove failure occurs during the winter. Therefore, it is extremely important to carry out work to eliminate the cause as soon as possible. Replacing the fan and motor of the stove with a VAZ 2114 is not a difficult job, even a not too experienced motorist can handle this. Repairing the fan is a little more difficult, but it can also be done in the garage.
