A/C compressor cycling conditions?
So I just replaced my Evap core, all o-rings, and upper hose w/ orifice tube; due to a leak.
Evap deff had leak and after vacuum I let it sit two hours; gauges didn't budge at all. I would assume at this point, no leak.
I charged it six or so days ago; at idle, one 12Oz can and another half 12Oz can that I still had connected to the hoses. The compressor never cycled; just stayed on and temp was super cold (and still is).
I observed the elec fan kicking on for a couple of seconds and seen the pressure drop fairly quickly. It would slowly build back up and fan would kick on again. Never noticed the compressor kicking off, again, just stayed on and temp was great. Is this normal operation?
Today, on my way to work, I could hear my compressor cycling while sitting at a light. Selection was recirc and fan low; temp was still very cold. Is this normal, do I have another leak, or was my charge too low to begin with?
