1974 Grand Am A/C Question

I just bought a 48,000 mile Grand Am. I charged the A/C and it is working. On Bi-Level I have all fan speeds, but on the A/C setting it blows full blast on all fan settings. It is not the hi blower relay as it is blowing like that on all fan settings. I don't think that is the way it is supposed to operate. Any idea what is wrong?
