Hi all,

I got an Astra G And am using op-com to see what my air con pressure is but I have a Few Questions as I cannot find what I'm looking for on the site.

1./ The air-con Pressure reading in op-com, is it the high pressure side or the low pressure side?

2./ What sort of pressure should I have showing in op-com ( I assume its a range of values is there a max and min?).

My air-com is working its just not very cold.

Thx All
