If your truck AC is blowing hot air, you should find the cause for this problem. The air conditioner is present in the truck, and it is an essential constituent of the truck. There are several new models of trucks with advanced functions. Every vehicle wears out due to several reasons, and people face difficulties due to this.
Why does my truck AC blow hot air? Your truck AC can blow hot air because of issues in the condenser, fault in the cooling fan, electrical fault, compressor, and reduced levels of refrigerant.
In the summer season, the drivers use the air conditioner of a truck in excess to protect them from the hot climate.
The air conditioner of the pickup frequently wears out due to numerous reasons. Occasionally, the AC of the vehicle stops working or blows warm air, and sometimes, the AC produces hot air from one side and cold air from the other side.
Why does my truck AC blow hot air?
You should not get panic if the air conditioner of your truck is blowing hot air. The cooling system of the pickup is present between the expansion valve and condenser.
Sometimes, the expansion valve and condenser wear out, and this causes problems in the system.
The primary function of this is to eliminate the moisture and heat inside. It eradicates the heat present inside the vehicle and then blows cold air.
The water valve often breaks, and due to this, the tools can stop working.
Overcharging the truck AC
Your device must not be overcharged. The additional temperature is not suitable for the air conditioner.
The refrigerant of the vehicle wears out due to overcharging. The cooling system depends on the coolant. If the refrigerant wears out, the AC does not work correctly.
The ability of the pickup to produce cold air reduces due to the excess charging. It is connected to the thermal expansion valve and sensor bulb.
The sensor bulb controls the flow of refrigerant and offers extreme operating compression.
The extreme operating compression sustains the flow of refrigerant. If the AC is overcharged, then the pressure of refrigerant increases.
Therefore, due to overcharging, the flow of refrigerant continuously rises, and the pressure of the coolant also rises.
The device is used to measure the pressure of the refrigerant. You should check the pressure of the coolant with the help of a gauge.
It is recommended that you should use smart technologies that correctly measure the pressure in the refrigerant.
Issues in condenser
The condenser is the crucial component; the liquid refrigerant flows from the compressor to the condenser.
The liquid refrigerant contains heat. The condenser eradicates the heat from the liquid coolant. When the heat eliminates from the liquid of the refrigerator, the cold air is produced through it.
The condenser works like a radiator, and if the condenser wears out, then it will not work correctly.
There are cylinders in the condenser that are connected to the cooling system. Occasionally, these cylinders are jammed due to the dirt, and due to this, the condenser stops working.
If you see any blockage in the tubes of the condenser, then you should unblock the pipes. It will not work correctly if the condenser breaks.
The machines often leak, and due to this, the condenser does not produce cold air from the cooling system.
You may feel the smell from the cooling system due to the breakage of the condenser. If you see the damage in the tubes, then you should show the condenser of your pickup to the expert mechanic.
Fault in cooling fan
A couple of cooling fan is present close to the condenser that aids the condenser to remove the heat from the liquid refrigerant.
It is not easy for the condenser to take away the heat from the fluid refrigerator. Therefore, the cooling fans work as a helper for the condenser.
The cooling fan removes the maximum amount of heat. It can be caused due to the breakage of the cooling fan.
When the cooling fan breaks, it stops working. The additional heat does not remove due to the breakage of the cooling fan.
It will not work due to the breakage of the cooling fan. Due to this, you may start sweating. The cooling fan often breaks due to the jerks.
It is recommended that you should check the cooling fans if it is not working smoothly. If you see that the cooling fan is broken, then you should replace the broken cooling fan with the new one.
If you are experienced in correcting the issue of cooling fans, then you should fix it.
If you don’t know how to manage the problem of cooling fans, then you should show the cooling fans to a professional mechanic. It will also make your truck to carry more weight.
The issue in the expansion valve
The fluid that flows in the compressor converts into vapors. The process of conversion of liquid into vapors is done due to the expansion valve.
The excess and low flow of refrigerant are not suitable for the expansion valve.
The performance decreases due to the problem in the expansion valve.
The other components of the vehicle also fail due to the problem in the expansion valve. This is common when you are transporting a motorcycle in a truck bed.
The expansion valve often blocks, and you can experience uncomfortable. The flow of air disrupts due to the issue in the expansion valve.
The other parts of the device start damaging due to the problem in the expansion valve. You should consult an expert mechanic to get rid of this problem.
The electrical components of the machine often wear out, and this results in the reduction of cold air.
The wires often break, and due to this, the cooling fans, compressors, and condensers do not work correctly.
The level of fluid refrigerant becomes low due to the electrical issue. You should regularly check the wires and fuses.
If you find any problem with the cables, then you should replace the old wires with the new one. If you convert your truck into a hybrid, it will improve better results.
The sensors are also present, which often wear out and block the working of condensers, compressors, or cooling fans.
The ventilation system usually wears out and send the damaged signals to the sensors.
Compressor giving you trouble
If the compressor wears out, then the refrigerant does not flow properly, and due to this, the vehicle may not work correctly.
The coolant flows through the tubes due to the compressor. The compressor often wears out if it is not used for an extended period.
For instance, you have not used the pickup in the winter season. Then, in the summer season, you have turned ON the air conditioner, then it will start with the shock.
The compressor may fail to work due to the long period, especially if you are trying to get your truck unstuck from snow.
The temperature of the compressor will maintain through this, and you will not face any problem. You should examine the status of your vehicle every week.
If you would not check the compressor every week, then the compressor would fail permanently.
Reduced level of refrigerant
The refrigerant is the crucial fluid that flows from the compressor to the condenser and then converts into vapors. Through this process, the cold air blows from the pickup.
The refrigerant often leaks, and disturb the overall functioning of the pickup. The flow of refrigerant decreases due to the leakage, and the fluid remains hot.
The air produced from the air conditioner is very hot, and people panic due to this.
The maximum pressure of the fluid decreases due to the leakage of refrigerant. This minimum pressure reduces the level of coolant.
If you notice the leakage in the refrigerant, then mend it. If you don’t know the solution to this problem, then you should consult the best mechanic. You should check the status of your equipment after two weeks.
