On a car with 25 year old hoses and condenser, they are more likely to blow out before the pressure reaches the cutoff switch rating.
In most cases yes, but a few times every summer I see a car idling in 90° heat have a loud bang underhood as something in the a/c gives out.I think the engineers who set the cutoff pressure took that into account.

I had a 4 cylinder manual Sentra that had a dead electric cooling fan. I'm pretty sure it had been dead for a long time before I realized it. It only got hot one time when sitting in a traffic jam for a half an hour on a 90 degree day. I was amused to find that cranking up the defroster to high was enough to cool the engine down to safe levels. Once traffic got moving a little bit (maybe 15 miles an hour) it went back down to normal.
Yeah, I meant the heater. The defrost vent was the least uncomfortable one to have it blowing out of on a hot day.Was it the defroster or the heater? I mentioned it earlier where I could tell my fan wasn't working at the time and I just cranked up the heat. But it was my 1995 Integra GS-R and it had an old style slider that controlled the heater core valve. I don't know enough about it to know if it was mechanical or some other way of controlling the valve.
Not sure how that would be done with something with electronic climate controls. Maybe turn off the A/C and select a high target temperature
