I have a 91 with the R134 AC that does not work well in the heat. It works ok when the weather is cool outside.
It only blows cold when the blower is on lower settings
Works better when its cool outside
I have washed out the radiator and condenser and there seems to be plenty of air flow... enough that it can hold a rag to the grill while parked.
I have added Freon with dye but I have not found any leaks.
I have confirmed that the electric fan comes one when the AC is on and the compressor clutch engages.
I dont know much about AC systems and need some help on this one... I tend to think the system isnt getting enough coolant and that could be why the hot outside temps kill my cooling.
Thoughts??
