Hi to all.
I have a 1991 940 with A/C retrofited to R134a.
Is it normal that the compressor continuously engages-disengages when
running, with a duty of 20-30 seconds ON and 5-10 seconds OFF?
The A/C systma has only the low pressure switch on receiver and a high
pressure security valve on bottom pipe.
Perhaps it requires more gas?
it would have charged about 1 Kg (35.27392 oz, 2.20462 lb)


many thanks.
