Blowing through the condenser doesn't mean a thing. It's a bypass type condenser and you can have 90% of it totally blocked and still blow through it. If you changed that compressor for an internal failure, then you need to change that condenser ASAP before you ruin the new compressor. Make sure the fan is pulling plenty of air too.
