Capture filter or a pre-filter
I had this problem and I think it is a hardware problem, I fixed it by cleaning the pc from dust using hair drier.
You have to take off the back cover and there is the filter. Do not wash it just blow on it and get off all the dust.
A filter drier for a cooling only condensing unit will have an arrow pointing in one direction. This is because the refrigerant that passes through it will always flow in the same direction. A heat pump filter drier must have the ability to allow the refrigerant to flow through it in either direction and so a filter drier that is made for a heat pump will have two arrows pointing in opposite directions.
Liquid-line filter drier.
It has what is called a receiver drier........ It does not have a cabin filter.
low pressure input side, but it really does not matter, because you have to pour in approx. 2 oz. of a/c pag or ester oil in there. That is if your refurring to an air conditioner unit.
its under the heating swicth
if you mean the filter/drier, then looking at the engine compartment, the left side near the jack
Filter any foreign particles via a fine mesh screen. These filters have a desiccant which will remove any small amount of moisture, trapped in the system.
The type we used to use on the job, had filter material inside of it which would flow down the suction line if you reversed it. It was made to only filter in the specified flow direction.
The filter/receiver/drier is an integral part of your car's A/C system that has been designed primarily to trap moisture, effectively removing it from the system and preventing corrosive damage to the A/C system. This 'drying' action is chemical in nature, so it can't go on endlessly, this is why it is very important to replace the filter/receiver/drier at intervals.
The filter/drier is under the hood, passenger side, along the inside of the strut tower. The cabin filter (if equipped) is under the dash passenger side. Only the three zone auto temp systems have a cabin filter.
