Perodua Myvi Compressor Repair Solution – Aircond High Side Pressure Is Low

About The Perodua Myvi Compressor

Perodua Myvi AC system require the Aircond compressor to compress the refrigerant and improve the AC heat releasing efficiency. Hence, Perodua Myvi Aircond will blow cold wind if the compressor able to function normally.

Generally, Perodua Myvi compressor is mount in the engine bay at the left bottom side of the engine. As a reference info, the car engine will use the belt to spin the aircond compressor in order to make it to operate. Hence, some car driver will switch off the aircond to reduce the compressor load and enhance the fuel economy and engine power output.

Nowadays, there are several type of the car aircond compressor which are rotary compressor and piston compressor. Firstly, the old Myvi or first generation Perodua Myvi is using a rotary compressor which is smaller. While the newer model Myvi are all using piston compressor which is bigger and able compress with more power.

As an additional info, there are two type of car AC compressor controller which are clutch and valve. Generally, both controllers are using the electric to control the on off switch and both controllers have their pro and cons. Normally, the valve controller will allow the car AC compressor to kick start smoothly. However, the valve will stuck easily and leak if the AC oil is dirty. On the other hand, Myvi clutch control AC compressor will cause jerking effect when kick start. But the clutch controller is more durable and it is will simplified the compressor problem troubleshoot process. Commonly, the workshop mechanic will check the clutch position to identify whether the AC compressor is cause of the problem.  

Symptom of Malfunction Perodua Myvi Compressor

If the Myvi compressor is not function nicely, the AC system will has the following symptoms :

  • Aircond blower does not blow cold air
  • Engine bay is having “sizzling” noise ( due to AC comp bearing/ piston )
  • The AC fan does not stop when the car aircond is on
  • Car AC system high side pressure is lower than the normal range

What is Aircond High Side Pressure

The car aircond high side pressure is indicating the refrigerant pressure at the section after the compressor. After the refrigerant is being compressed by the compressor, the pressure reading will become higher when compare to the other section.

As a reference, Perodua Myvi high side pressure will normally drop in the range of 150psi to 210psi depend on the environment temperature. If the environment temperature is higher, the high side pressure will be higher. This is because the compressor will do more work to compress the refrigerant will increase the heat releasing effacing while the refrigerant is in the condenser.

How To Check the Myvi AC High Side Pressure ?

The gauge meter can detect the pressure of the Myvi AC high side pressure. When checking the car AC system, the mechanic will plug the gauge meter at the inlet or socket which is mounted with AC piping. While the Myvi AC compressor is operating, the gauge meter will show the high side pressure value.

Why Aircond High Side Pressure Low

When Perodua Myvi aircond compressor has mechanical problem, the compressor will hardly compress the refrigerant. As a result, the high side pressure will become low and fall out of the normal range which is below 150psi.

Besides, the high side pressure will become lower when the AC is running out of refrigerant. If the car AC system does not have enough refrigerant, the low side pressure and high side pressure are lower than normal.

Outcome of High Side Pressure Become Low

While the high side pressure is low, the refrigerant is not compressed to a correct level. Hence, the refrigerant will not able to release the heat as fast as possible while the refrigerant is circulating in the condenser. As a result, the refrigerant will not become cold after flowing through the evaporator and cooling coil. So, the AC blower will not blow cold air especially when the environment temperature is high or the car is at idle state. In short, Perodua Myvi aircond air will be hot if the high side pressure is low.

Myvi Aircond Repair And Compressor Replacement Service

The car ac repair workshop is providing the solution to repair Myvi aircond compressor problem. Generally, the ac repair workshop mechanic will inspect the aircond system by checking the high side and low side pressure. If the gauge meter is showing normal low side pressure value and below normal level high side pressure, the compressor may have some problem.

On the other hand, the workshop mechanic will also check Perodua Myvi aircond compressor clutch. Generally, the compressor will not function if the clutch is having problem or not function properly.

After confirming the compressor is malfunction, the mechanic will suggest the compressor selection and  quote Perodua Myvi owner. If the car owner agreed with the quote, the mechanic will start Perodua Myvi compressor replacement process. Firstly, the workshop mechanic will flush or release the refrigerant. Next, the mechanic will remove the compressor from the mounting. Then, the mechanic will install the new compressor. Additionally, most of the workshop will suggest the car owner to proceed with the solution to change the O ring to prevent leakage. Lastly, the workshop will vacuum the AC system to remove the moist and refill the refrigerant into the AC.

Part Selection And Options

As a reference info, there are several car AC compressor options which are suitable for replacing Perodua Myvi malfunction compressor. Generally, different compressor options have different quality, durability, warranty conditions and price. Hence, Myvi owner can decide to use either OEM, recon, no-brand or ori parts.

Recon Part

Literally, recon part is having good demand because it has lower price. Thus, recon AC compressor is a good alternative which will help to reduce the AC repair cost significantly. Furthermore, some recon part are actual Denso product which some car owner feel it has better efficiency.

No-Brand Part

Some car ac repair workshop is offering no-brand AC parts as the alternative options. This is because some Myvi owner does not want to use recon parts and expensive Denso or OEM parts. Thus, Perodua Myvi owner will try to select no-brand compressor to replace the malfunction part. Generally, the price of the no-brand part are lower but the function and dimension are quite similar to the actual part.

OEM Perodua Myvi Compressor ( eg. SWJ )

SWJ Myvi compressor is a popular options in the car ac repair sector. This is because SWJ compressor is having good reputation and quality. Furthermore, the price is much lower than the Denso Perodua Myvi compressor. Thus, many Perodua Myvi owner is happy to use SWJ part when their Myvi AC part is damage and require replacement.

Denso AC Compressor

Actually, Denso compressor is original Perodua Myvi compressor because Perodua does not manufacture and supply their own compressor. Generally, Denso AC part is having good quality control and durability. Furthermore, the mechanical compressing performance of the Denso part is very promising. Thus, many Myvi owner will still prefer to Denso AC spare part. If wish to know the detail and price list of the Denso AC parts and other AC parts such as SWJ or recon, please contact us. Hence, we will prepare the reference price list for you and offer you the solution to check your car AC parts and system.
