95 Toyota Tercel, 334K miles, 4 cyl - A/C works for 10 minutes then gradually blows warmer air. Vent temperatures increase from 54 degF to over 80. Low pressure side = 45 psi, high = 225 psi. When the engine is really warm, I can see the pressures changing somewhat (which I think means that the expansion valve is working). Compressor never cycles but stays on constantly. I would love suggestions on how to pinpoint the problem. Thanks in advance.
