RE: 92 prizm a/c
One of the other moderators seems to have good connections for charts and such but I would start with the fuse box and a test light.

Let me ask how you know there is good pressure?

If the compressor comes on then you really mean the blower is not working, right?

If the compressor does not run then I would check the low pressure switch to be sure it's not keeping the compressor from running. You can by-pass it with a paper clip stuck into the terminals and see if you get cold air, or you can run a jumper wire to the compressor terminal with 12 volts.

Do not run in this mode for long with low pressure because the oil does not circulate well unless there's enough refridgerant in the system.
