Just in case you haven't checked it, is the fuse blown? (Marked ELC on the fuse panel). If the compressor is bad, I think a couple of people had ones they removed for sale in the last month or so.

Suncore industries sells refurbished ones for about $80-100. The typhoon may not be in there but the 92-93 caddies have the same pump.
