2005 Volvo S80: Necessary to Replace Receiver/Drier For A/c?

When the Vehicle A/C system is disassembled or open or taken Apart.
Its mostly necessary to replace the Receiver/ Drier part.


Yes, the receiver/drier contains what is called a deccisant bag, which is designed to absorb moisture in the system. When you open up the system to replace any parts, the deccisant bag fills with moisture from the atmosphere and its effectiveness is greatly reduced.

You can decline to have it replaced, but if you do so then  there will be no warranty on the job of getting the proper cooling from A/C system, as you have declined required work. The system likely will not get as cold either since the receiver drier can no longer pull the moisture out of the system.

So getting this component replaced.If the A/C Repair center is recommending it.

This details will help.
Thanks.

2006 Volvo S40: A/C Runs Intermittently?

Air conditioner is running sometimes for a while then just stops.
In this cases you will notice that A/c stops working but fan just keeps on running.

In this types of problem there is no one single possibility.There are multiple possibilities that can cause this problem.

First thing you have to inspect is compressor.Is the compressor engaging or not engaging when A/c stops running.


there are many possible causes:

-low refrigerant
-faulty compressor
-faulty compressor clutch coil
-faulty pressure switch
-short/open in wiring harness
-internal fault in climate control panel
-fault in ecm
-restriction in the condensor
-restriction in the expansion valve

Unfortunately, as you can see, there is no one single cause. The first step is to read the high and low pressure readings with an ac manifold gage on a test drive to see what the readings are when it quit blowing cold air.

This will let you know or confirm if there is any restriction in either the condensor or expansion valve, if refrigerant is low, or if the compressor disengages.

If compressor disengages, then electrical testing has to be performed to see why and where the signal is lost.

I really wish I could tell you that it is one single thing and you just need to replace "X part", but that is not the case as professional testing is really required for this in order to find the underlying cause out of the several possible causes.



This detail will help.
Thanks.

1997 Buick Lesabre: A/C stopped Blowing cold?

On Buick Lesabre 1997 Year model Vehicle it has Automatic Temperature  controls with separate Controls for driver's and passenger side temperature adjustment.

In this case first the A/C stopped blowing cold at passenger side and then stopped blowing at driver side.



Ok, the automatic climate control does not have vacuum controls. The blend doors are electronically controlled by the climate control unit and actuators at the blend doors.

Hence one side stopped working and then the other, this majorly indicates that the climate control module failing rather than both the driver and passenger side blend door.

If the shop doing the work does not have a scan tool that can test the climate control unit and the temperature blend door actuators, you will need to have another shop test it or have a dealer test the system.

This needs to be done before spending money on replacing the doors when it is unlikely that both have failed at once.

This details will help.
Thanks.

AC stops working when it gets warm outside?

Ac stops running on hot conditions this indicates few possibilities. Check the refrigerant level in the compressor of car ac.If its low then car will compressor will overheat and stops running. Also check the coolant level.If its low then it needs to be full.Also check if there any leak of the coolant.Get the ac pressure test done.It can be done at any local car garage.This will confirm whether there is refrigerant or coolant leak in the system causing the ac to stop after sometime.If coolant and refrigerant all checked OK.Then the thermostat needs to be checked.When the car temperature reaches certain temp the cooling fan turn on and cools the thermostat.But if the cooling fan stopping after ac turns off then thermostat needs to be checked.Also connect the fan connections to car battery and check if the fan is running directly.Check the voltage at fan terminals.It should show exact 12 volt.If less then that then fan is faulty and needs replacement.If fan tested OK then thermostat needs to be checked and replaced.Also check the coolant temperature sensor.If this sensor is not working then this will make the vehicle overheat and this will stop the ac and it stops running.
