Finacky AC- Works if I start car in AC but turns warm, won't work if I dont
My AC is finacky. If I start the car and the AC is "ON", it works beautifully well for about 45 minutes and then it goes warm. If I start the car w/o AC but THEN turn on AC it doesnt work at all. If I start the car on AC and then I turn AC off and then try to turn it back on it doesnt work.
pressure seems fairly decent in the AC lines so its not a leak issue. I dont really understand AC well enough to diagnose it. Any takers?

Sounds alot like what mines doing and I narrowed it down to the clutch. Because once the compressor heats up and the clutch disengages it just won't re-engage until the entire motor cools down and the compressor is cool again. It's like $80 for the clutch off ebay.

some of your vacuum lines are probably cracked. The vac lines that switch your vents and open/close the flow of air over your heater core.
It is one of those expensive jobs that require inexpensive parts. The problem is you need to get inside your dash.
