The A/C works fine for about 15 minutes as if it is brand new and then starts blowing luke warm air.

Have you checked the refrigerant (R-12 or R-134)? Low refrigerant can cause the evaporator core to freeze up after a while, preventing air from passing through it. You sometimes notice some white ice fog from the air vents prior to the evaporator totally freezing up. Another symptom is reduced air output from the vents. It's at least worth a look since checking the refrigerant is really easy.
