Post '01 Olds Van Troubles

Any one fixed or repaired an Olds Van with:
AC blows warm air (compressor on/coolant full)
High RPM idle intermittently (IAC Valve replaced)
Radiator Fans do not come on (fans and fuses ok)
No "service engine soon" or diagnostics are tripped.

I suspect possible PCM trouble. Anybody??

First thing that comes to mind is a vacuum leak. This could cause both a loss of ability to control the ac and an erratic idle. Cooling fans could be bad temp sensor. All this stuff does have computer relations, so that's not out of the question. Might not be a good candidate for diy troubleshooting.
