Myvi Hot Aircon Problem When Engine Idle
When the sun is hot, Perodua Myvi aircon sometime cannot cool down the hot temperature especially while the engine is at idle stage. Besides, hot aircon issue will also happen when the car is at the traffic jam. Generally, the main causes are because some part of the aircon has degrade or malfunction. When the aircon parts is degrade, the aircon performance will reduce. Hence, the side effect will become very significant when the environment temperature is high.
Why Myvi Aircon Does Not Blow Cold Wind When Engine Idle Or Traffic Jam?
The aircon performance will reduce because the certain parts such as compressor, condenser or sealing part are degraded. Generally, Myvi aircon system consist a lot of parts, sensor, piping and seal. Thus, all these parts must be in good condition in order to work together to complete the aircon system.
If the condenser condition is bad or the compressor is weak, Myvi aircon will hardly blow cold air when it is idle or stuck in traffic jam. This is because the refrigerant gas will hardly release the heat effectively if the condenser or compressor cannot function properly. Thus, Myvi aircon system require more air flow to cool down the refrigerant gas. Hence, Myvi aircon will become hot at idle stage because the car is not moving and the air flow through the condenser is low.
As a reference info, Myvi aircon blow hot air when its engine is idle or jam in the traffic might due to the problem as below:
- Perodua Myvi aircon condenser has become dirty or damage
- The fan cannot function properly
- Aircon system is lacking of refrigerant
- AC Compressor has become weak
AC Condenser Is Dirty Or Damage
The condenser is the part or section where the refrigerant will release the heat out from the AC system. In other words, dirty condenser will cause the AC system heat releasing efficiency to reduce significantly. This is because the dust and dirty substance will reduce the air flow and cause the heat hardly to escape. So, the hot AC problem will become more obvious when the car is not moving while the car is idle or stuck in the traffic jam.
On the other hand, the condenser will easy to become damage if it is hit by the stone chip. This is because the condenser air flow fin is quite thin and it will damage and leak if the stone chip hit with high impact. After the condenser is leaking, the refrigerant gas will leak and cause the AC efficiency to reduce. Hence, Myvi AC will become hot and fail to blow cold air if the condenser is damage.
Fan Issue
Other than the condenser, the car aircon system require the fan to form the air flow and cool down the refrigerant. Generally, the fan will blow the condenser and let the wind to carry the heat out from the condenser especially when the car is idle. Hence, the car aircon condenser will not has any air flow if the fan does not function when the car is at idle stage. As a result, Myvi aircon wind will become hot when the fan cannot function while the car is idle or facing traffic jam issue.
Lack Of AC Refrigerant
Myvi car aircon system need the R134a refrigerant gas to remove the heat from the cabin and cool down the temperature. If the AC system is lacking of refrigerant gas, the car AC performance will reduce because the AC cannot remove the heat fast enough. Hence, the hot aircon problem will become serious if the environment temperature is high and the car is not moving to enhance the air blow.
Commonly, Myvi aircon system will lack of refrigerant gas because the aircon system has leakage problem. Additionally, Perodua Myvi aircon will face refrigerant gas lacking problem because does not go through regular AC maintenance service. Hence, the AC system refrigerant content will reduce from time to time after a operating for a period of time.
Weak Compressor
As an additional info, weak compressor will also cause Perodua Myvi aircon to face performance reduction issue when the air flow is low. This is because weak compressor will not able to compress the refrigerant effectively and enhance the heat release process. Thus, the heat will trap in the the refrigerant flow when the air flow is too low while the car is not moving. As a result, the cooling coil does not have cold refrigerant to cool down the blower wind and cabin temperature.
How To Troubleshoot Myvi Hot Aircon When Idle Or Traffic Jam?
There are several methods and ways for checking the Myvi hot aircon problem while the car is idle or stuck in the traffic jam. Generally, the high side and low side pressure will show the response effect if Myvi aircon system has problem. Thus, the mechanic will use the gauge meter to read the high side and low side pressure.
Next, the mechanic of the car aircon repair workshop will also review the condenser condition. If there is any leakage or oil spot, the condenser is damage and having leaking problem. On the other hand, the mechanic will also able to identify dirty condenser by the condenser reviewing process.
After the reviewing process, the workshop will summary the possible causes and propose the solution for Myvi car owner. Then, the workshop will start the aircon repairing process after Myvi owner accept the solution and quotation.
How To Fix And Repair Myvi Hot Aircon?
Sometimes, refrigerant gas refilling service will able to fix the hot Myvi aircon problem while the car is staying in idle condition. Next, the workshop will change the AC part such as condenser or compressor if the malfunction parts are the causes of the problem. Hence, Myvi will have an efficient car aircon system when the environment is hot and the car is stay in idle or traffic jam condition.
