Default How to flush the A/C evaporator of the car?

Hello,
How to flush the A/C evaporator of my car? Is it in the direction of the flowing of the R-134 only? Or both ways the flowing direction and the opposite direction?

thanks for help.

I'd do it both directions. Don't forget that the expansion valve might also have material that is clogging it. And remember to add compressor oil when you do this repair.

:I read in the net that

1- compressor.
2- accumelator / drier.
expansion valve -3.
4- condenser of the late modern cars.
5- compressor muffling parts.
6- orifice tube.

all of the above can not be flushed or else they will get damaged.
only flush the evaporator and piping of the A/C system of the car.

and just replace the orifice tube with a new one.

the filter of the A/C system can be cleaned of dust by compressed air ( air blower ) or can be replaced with a new one.

by the way, what is the amount in milliliter of A/C system oil I have to add to the A/C system of the car after doing the flush?

thanks for help.
