If the compressor froze up, then yes your going to have to replace the condenser, and most likely that hose assembly hooks up to it. Also your not going to like this one, but if it sent debris through the system then you need to pull the rear A/C unit out and change the screen in the expansion valve. These compressors don't normally lock up, but it sounds like you got bit by the classic dual air bug. With dual air you must always run both units when the A/C is on. normally what kills teh compressor is when you run the A/C and don't turn the fan on for the rear unit. this causes it to close off the rear expansion valve since the rear A/C isn't running, and oil gets trapped in the rear A/C line. Once enough oil gets trapped in there the compressor eventually runs dry and locks up. GM knows about this issue, and came out with a revised expansion valve for it. I don't envy you at all as your going to HATE doing this job.
