Where is the blower gear switch generally installed?

It's usually installed on the side, and it's usually like this, and there are also assembly switches that are connected to other devices.

So it's up to you.

In the conventional automobile air conditioner, the speed of the blower is regulated, and the voltage is adjusted by using the resistance value in the circuit to achieve the purpose of adjusting the speed of the fan. Generally, the resistance of the low-grade string is large, the resistance of the medium-grade string is small, and the high-end string does not string resistance. The principle of this method is relatively simple, the cost of parts is also low, and the maintenance is convenient.

However, the adjustment range is small, and a lot of power is consumed on the resistor.

The blower gear switch is generally installed in **? It depends on your shares and the installation of ** switches? You can open it casually, but you can't hurt it yet.

The blower gear switch should have a button in place of the blower baffle.

The blower gear switch is generally installed in **? After the blower is turned on, it has a yes. As long as the electronic module is called a block, the wire that comes out of that block is connected to the gear switch.

Under normal circumstances, it should be installed on the underside of its control panel, and the positive circulation is relatively normal and within a reasonable development range.

The gear of the blower is generally placed in a convenient place to operate, and some are placed below the switching power supply.

I ask you that the gear switch is generally installed in **, this should be installed on the side, and you can check it out at the blower store.

If he switches on and off, it is usually installed on his left side or on top, which is for safety reasons, so you can know it at a glance.

The car blower switch is the switch that adjusts the wind speed:

1. The external circulation is the temperature of the natural wind outside the car, but it will be slightly higher, because the air inlet of the external circulation of the air conditioner is basically between the lower edge of the front windshield and the engine compartment, which will bring the temperature into the cabin; If it is an internal circulation, it is the temperature in the car that blows out;

2. If the temperature is high, the cooling water heat of the engine passes through the evaporator (small water tank radiator) in the air conditioning system, and the hot air is adjusted through the opening angle of the partition with the natural wind.

It must be installed not far from the blower for easy monitoring and operation.

The blower gear switch is generally installed behind the blower, which does not affect the use of the blower.

The blower gear is generally mounted on the side of the blower.

Not necessarily. Some are set up with control rooms.

The small ones are set up in a nearby switch box.

To install the rotary gear switch of the electric fan, see that there is a gap in the switch button, which is the positioning slot, and it can be inserted accordingly.

As long as you find the two main lines, you can connect them directly to the power, plug in the plug and turn it on, dial it off, there are many lines, and there are many functions. The easiest way is to turn the switch on, plug in the latch when it is on, and unplug it when it is off.

There are two terminals in the gear switch, one in and one out to control the fan live wire, and the fan neutral line is directly in the common neutral line that has been protected by leakage, note that the gear switch is connected in series between the fan live wire and the power live wire.

Look at the switch button has a gap, which is the positioning slot, and the corresponding insertion can be done.

Connect the zero wire to the common zero, and then connect the phase wire to the lower circle end of the three gear switches, so that Lu Chun can realize it.

I haven't done it concretely, it's theoretically possible.

If you can't, you can find a dedicated electrician and let him do it according to my ideas.

In order to open the wire head, generally speaking, there will be an arrangement in the lower right corner and the lower right corner.

This case is different, and the wiring diagram of the fan is different according to different specifications.

The blower resistor is on the right rear side of the accelerator pedal, between the firewall and the bellows. Resistors are generally referred to as resistors in daily life. It is a current limiting element, after the resistor is connected to the circuit, the resistance value of the resistor is fixed, generally two pins, which can limit the current through the branch it is connected to.

Negative pressure fans are generally not equipped with gear switches, as if they are more famous: Tuhe and Jiafeng negative pressure fans do not provide speed switches. But if you have to use it, you can use it, and you can directly install a 380V inverter.

The car air conditioner has only four gears with wind, and 123 gears have no wind. The cause of the failure is that the resistance of the blower is damaged, resulting in the blower having only four gears and no 123 gears. Damaged blower switches can also cause this failure.

The 4th gear of the air conditioner blower is a direct gear, and it is recommended to check whether the wiring harness between the blower switch and the blower resistor is short to the ground, if the short circuit is recommended, if the wiring harness is not short-circuited, replace the blower resistor.

If there is a problem with the blower, you can contact the manufacturer directly. Second, you can also contact Sazhen Company, which is a company that has done a good job in products and after-sales maintenance.
