Quick AC/Cooling Question
#1

So I just got back from a 4hr road trip through the mountains. Truck did fine coming and going. Two days later I noticed it running hotter than normal (215-222) Also realized the AC wasn't cooling off either. Get home to see the compressor has leaked freon and the coolant was low. I added coolant but not freon. I figure if it leaked like that what's the point in trying to fill it. Just going to buy a new compressor.
But my question is why isn't my e-fan coming on? Is it because the ac compressor isn't engaging? I feel like the fan should come on regardless right?

Is the aftermarket fan controlled by the factory wiring, or does this fan have it's own thermistor for control? In other words, if it's an aftermarket fan with aftermarket wiring, you'll have to know how it was wired to know whether it is wired to come on when the A/C is turned on, only when the compressor field coil gets power, or if it isn't wired in for the A/C at all.

Yep, agreed based on prior operation. Do you have a test light so you can test for voltage to the fan when the A/C is on? A multimeter can work too, but it won't load the circuit like a test light will in order to make sure there's current making it to the fan. A loose/dirty/corroded connection is not as easy to identify with a multimeter due to its high input impedance.
