I had my alternator replaced a few days ago as it was bad(brake and
battery light flashing) and now the ac compressor will not turn on. Of
course the shop is not taking any responsibility for this. They have
done a pressure test and looks good. They have tried to troubleshoot
via electrical diag tests and have found nothing so they are leaning
toward the PCM being bad. Does this sound correct as I am having no
other issues with the car except the AC.

Thanks

should be no connection,,pardon the pun, between the two.

check that they didnt break loose the wire to the AC compressor.

Here's a long shot. Check the cigarette lighter fuse. Replace if bad/blown.
It's what caused my AC not to work in my 97 Nissan PU.
In my truck, the cig lighter and the AC control is on the same circuit
and controlled by the lighter fuse.

The shop has probably inadvertantly disconnected the compressor coil
connection. Trace that single wire in the engine compartment.
