[s-cars] AC cut out

[Robert Rossato]

This is a common occurrence on really hot days.  When it happens on mine
I let it sit for about 30 seconds after it's kicked off and then turn it
on again.  Usually stays on after that.  May sometimes require a second
try.  I really think it's the high pressure switch in the system that
may have drifted with age and the higher pressure in the system on hot
days takes it over the edge.  Try replacing the switch.
