Its really kind of random. Yes I do notice that the compressor kicks out under acceleration then comes back on. I thought maybe for a while it was the kick down switch. I popped the hood the other day and I turned the climate control off and then back on. I think I am leaning towards the temperature control switch. If it was low pressure would it come on and run for 40 miles or more sometimes?
