Its wintertime here so the ac isn't running but will it still cycle off and on to build pressure if the charge is low? Also if it is low can you add refrigerant when it is too cold for the ac to kick on? I've tried it with the climate control on auto and off and at idle in and out of gear it only does it when its on. Any ideas what it could be.
The bottles specify setting it to max cool to measure and then if needed fill it. Does just engaging the compressor perform the same function to get an accurate measure of pressure. The same as using the max-ac or norm ac that is actually cooling and using refrigerant. The gauge showed 35-36 psi which is within the normal range.
