'92 Estate Wagon A/C Questions

Hi, I have a few questions about getting my A/C to work better.
1. What are the high/low side pressures for this specific car? The general A/C handbook in Autozone did not have pressures listed for '92.
2. My A/C currently blows cold, but even on the highest fan setting not much air comes out of the vents. I can tell it's blowing hard since the fan is roaring but there is only a faint breeze. Is there a cabin air filter that could be plugged? Any other suggestions?
3. My condenser had a big hole in it, so I replaced it with a part from O'Reillys. I was in a rush, so I did not notice until later that the replacement condenser only had a single bank of tubes whereas the original condenser had two banks of tubes (basically the old condenser was a lot thicker). Any ideas on how much this will impact my A/C performance? Anyone else using a setup like this?

1. What are the high/low side pressures for this specific car? The general A/C handbook in Autozone did not have pressures listed for '92. If you still have R12 in the system, the low side should be about 32 psig and the high side between 180-280 depending on ambient temperature and demand.
2. My A/C currently blows cold, but even on the highest fan setting not much air comes out of the vents. I can tell it's blowing hard since the fan is roaring but there is only a faint breeze. Is there a cabin air filter that could be plugged? Any other suggestions? No cabin air filter in the 92! You must have a restriction in the evaporator, or one of the blend doors not functioning properly. Check all vacuum lines from the engine to the AC programmer under the dash then, check from the programmer to the actuators.

Always try to use the same, or larger condenser than OEM, especially, if your system has been converted to R134a.
