Unhappy Olds Sillhouette Gremlins

My 2001 Olds Van suddenly starts acting up after 133K miles:
Idle speed erratic and A/C blows hot air.

I replaced the IAC valve troubleshooting the idle problem and that didn't help. Then the A/C quit working, not a gradual loss of cooling, but a hot air blast. The A/C compressor is engaged.

Chilton/Haynes indicates possible PCM diagnostics/replacement needed.

Anybody got any suggestions?
