please give me pressure knowledge for refrigerator
Anything 1995 and newer uses R134a refrigerant.
All vehicles after 1993 I believe use R-134a
R134a
R134a
R134a
R134a
R134aR134a
R134a
It is icing over and is either low of refrigerant or the coils are dirty.
Would have been built for R12, can be converted to R134a.
No, the A/C system on a 2004 uses R134a, an alternative to freon (R12) which was phased out in the 1990s.
Although your VW uses refrigerant (one trade name is Freon) in its A/C system it has no specific "container". It is all a closed system, so technically the refrigerant circuit is a container. Could you be more specific?
