The air conditioning on my father's 1997 Ford Escort quits putting out
cool air when the temperature outside is above 95 degrees. He has had
it checked by a Ford dealership and they said the AC works fine. Does
anyone have any thoughts as to why the AC would do this? And is there a
way to fix it?
The overall pressure in an A/C system rises as the outside temp rises.
There's a high-pressure cutoff switch on the high side that may be cutting
out. Perhaps your system is overfilled or has air in it?
I would bring it to another dealer or mechanic who knows a bit more about
A/C systems and will properly test it, preferably outside when it's 95+
