Hello guys
I have a 2001 X5 BMW 4.4

I've been having problems with the a/c compressor coming on intermittently.
When it does kick in, a/c blows nice and cold.

Grabbed a set a gauges from autozone here are the following results with an outside temp of 65 degrees
Engine off
High side 130
Low side 25

Engine on ( I hooked the compressor to power source)
High side 75
Low side 59

Can anyone give me an indication of what the issue may be?
