The old Jetta heater of the 05 model is not hot, and there are several reasons:

First, the air conditioning filter of the vehicle is blocked, which will make the air conditioning system less intake, there is not enough air volume, it will not be able to blow out the warm air, and it will not be very hot, just replace the air conditioning filter.

Second, the air duct is blocked, that is, there are foreign objects in the air duct, which blocks the air duct, and it will be restored after dredging.

3. The small water tank of warm air is blocked, which will make no hot water enter the small water tank, and there will be no heat source, just clean the small water tank.

Fourth, the cooling water of the vehicle is missing, so that the water will not enter the small water tank, so it will not be hot, just add cooling water, the specific operation steps are as follows:

1. Open the door on this side of the cab.

2. Pull the hood switch on the left side of the driver's leg.

3. Lift the hood of the engine upwards.

4. Support the hood with a support rod to ensure that the support is firm and avoid danger.

5. Add cooling water to the water tank.

Notes:1. Add cooling water of the same specification.

2. Add cooling water of the same color.

The lack of heat can be divided into two reasons, one is caused by the engine cooling system, and the other is caused by the poor work of the control mechanism of the warm air. Check if there is a lack of coolant, the lack of coolant only needs to be replenished. Check whether the thermostat is damaged, the thermostat is damaged and needs to be replaced with a new thermostat.

The water temperature of the car is normal but the warm air is not hot, it may be that the water pump or cooling circuit is blocked, resulting in problems with the engine cooling system, the coolant can not be circulated, and the coolant cannot be sent to the warm air water tank, so that the warm air is not hot.

It is also possible that the vehicle's water pump impeller is damaged or lost, resulting in a decrease in the amount of water flowing through the water tank, resulting in the warm air not being hot, and a new water pump impeller needs to be replaced.

The air conditioner filter is blocked, and there is a problem with the control mechanism of the warm air, so that the air volume of the blower blowing into the car is not enough, or the distribution of hot and cold air is unreasonable, and the phenomenon of warm air is not hot. If the heater water valve is damaged, it may cause the coolant to not enter the heater tank, causing the heater to not heat up.

Hello, in this case, first check whether the liquid level height of the antifreeze is normal, if it is too low, it needs to be replenished in time, check whether the water temperature of the engine is normal, if the water temperature is normal, this is generally due to the blockage of the warm air water tank, the circulation is not smooth, this situation will occur, the warm air water tank needs to be cleaned to ensure that the water circulation is restored to normal. Timely maintenance to ensure stable, comfortable and safe driving, thank you.

The warm air is not hot, if there is no shortage of water, the water temperature meter shows 90, touch the two water pipes of the warm air is warm or not hot at all, and then touch it, the top of the water tank is not very hot, if: the warm air water pipe is warm but the big water tank is very hot, basically the thermostat is broken, resulting in the heat dissipation of the large water tank, so that the warm air will not be hot, do not blindly listen to them say that the warm air water tank is blocked, because the antifreeze is anti-corrosion, the water tank is impossible to block.

The main thing is to check whether the antifreeze is enough, if the antifreeze is not lacking, it may be that the warm air tank is blocked, and it is more new.

If the Jetta warm air is not hot, you can first see if the heating mode is selected on the air conditioning control panel, or it may be that the air conditioner warm air tank pipe or warm water pipe valve is blocked, or it may be that the internal windshield of the air conditioning system is stuck or falling off, which affects the lack of warm air, and the heating control system has a problem and must go back to the 4S shop for inspection and maintenance.

The car heater system can provide heating, defrosting, and adjusting temperature and humidity. In cold winters (even late autumn and early spring), car heaters can heat the interior of the car and increase the temperature inside. In winter, spring and autumn, when the air humidity is high and the temperature difference between the inside and outside of the car is large, frost and fog will form on the window glass, which will affect the driver's line of sight and is not conducive to driving safety.

In this case, turning on the heater system removes frost and fog from the window glass.

The vehicle heating system is not hot can be divided into two reasons, one is caused by the engine cooling system, and the other is caused by the poor work of the heating control mechanism. The judgment method is also relatively easy, check the temperature of the two inlet pipes of the small water tank of the warm air, if the two pipes are hot enough, it means that the air volume control mechanism is a problem. If both pipes are cold, or one is hot and the other is cold, it is a problem with the cooling system.

Check whether there is a lack of coolant, and the lack of coolant only needs to be replenished. Check whether the thermostat is damaged or not installed, and if the thermostat is damaged or not installed, you only need to replace and install a new thermostat.

The vehicle heater system is not hot can be divided into two reasons, one is caused by the engine cooling system, and the other is caused by the poor work of the control mechanism of the heater. The method of judging is very simple, look at the temperature of the two inlet pipes of the small water tank of the warm air, if the two pipes are hot enough, it means that the air volume control mechanism is a problem, on the contrary, if the two water pipes are cold, or one is hot and one is cold, it means that it is a problem with the cooling system.

After the warm air small water tank is blocked, the hot water does not pass through the small water tank, resulting in the phenomenon of no warm air, and the blockage of the warm air small water tank may cause the cold air to blow out, and the reason for this phenomenon is that the owner does not replace the antifreeze for a long time. If you do not clean the air conditioning duct for a long time, it is also easy to have a small heating tank blockage, it is recommended that the owner do a more comprehensive maintenance of the car's heating system before the winter comes.

Summary. Hello, I am very happy to answer your car master exclusive technician attentively and sincerely answer your car questions, for you to find solutions and methods to ask questions, the first is to press the AC switch, measure whether the air conditioning compressor plug has power, if there is power supply, replace the compressor.

Second, if there is no power supply, there is no need to check whether the air conditioning system is defective, whether the engine control unit has the fault of the air conditioning pressure sensor, and whether the air conditioning control line is abnormal.

17 years**Jetta air conditioner compressor does not turn, fan does not turn.

Hello, don't click to end, I'm textual to give you the full answer, 2-3 minutes.

Hello, I am very happy to answer for you Your car master Nachang brother technician concentrate on your intentions and sincerely answer your car questions, and find solutions and methods for you to ask questions, first of all, press the AC switch, measure whether the air conditioning compressor plug has power supply, and replace the compressor if there is power supply. Second, if there is no power supply, there is no need to check whether the air conditioning system is missing, whether the engine control unit has the fault of the air conditioning pressure sensor, and whether the air conditioning control circuit is abnormal.

There is electricity in the compressor plug.

If there is electricity in the compressor plug, the compressor is broken and the compressor needs to be replaced.

Summary. Check if there is no thermostat. If there is no thermostat, the waterway is directly circulating, that is, it has been dissipating heat through the water tank, and after running, there will be natural wind constantly blowing the water tank, causing the temperature to drop.

The old Jetta heater is not hot when it runs.

Hello, I'm helping you sort out the answers to your questions, please wait a moment

What about people. Check if there is no thermostat. If there is no thermostat, the waterway is directly circulating, that is, it has been dissipating heat through the water tank, and after running, there will be natural wind constantly blowing the water tank, causing the temperature to drop.

The thermostat is fine.

Just change the antifreeze and clean the warm air tank.

If the water temperature pointer is not lowered, it is blocked in the hot water tank, and if the water temperature meter pointer is also lowered, it is a problem with the thermostat.

It's all normal.

The inlet and return water of the warm air tank are hot.

The thermostat has just been replaced.

Whether to change the antifreeze or not has nothing to do with whether the warm air is hot or not, and whether the warm air is not hot is only related to whether it is circulating or not. If the thermostat is normal, the small circulation is normal, the inlet and outlet pipes of the warm water tank are hot, and the air volume remains unchanged, then there is no such problem, you still check whether the upper and lower pipes of the water tank are the same as the hot handle. Check when the heater is not hot.

Jetta's small water pipes are prone to clogging. After the blockage, the small water pipe of the auxiliary kettle does not produce water.

The small water pipe is running and the water is coming out all the time, which proves that the small circulation is normal and the water pump is normal, otherwise check whether the small water pipe is blocked, and if it is not blocked, it is a pump problem.

The water in the warm air tank does not participate in the big circulation, so when the water in the water tank is not hot, the warm water tank is already hot, and it is not affected by the speed of the vehicle. Unless the thermostat is always on, or the pump is not circulating.

If I can help you, please give me a thumbs up Thank you!

There may be several reasons why the Jetta fan does not spin and is as follows:

1.Power failure: Check whether the power supply of the fan is normal and plugged in.

2.Motor failure: The fan motor may fail and the motor needs to be replaced.

3.Fan blades getting stuck: Fan blades may be stuck with dust or other substances and need to be cleaned.

4.Aging fan bearings: Fan bearings may be aging and the bearings need to be replaced.

5.Controller failure: The fan controller may be faulty and the controller needs to be replaced.

It is recommended that you check whether the power supply and fan blades are stuck first, and if the problem persists, it is recommended to find a professional to repair it.
