its possible if the refridgerant level got low enough, it may gone into suction on the low side and drawn in some air which would make it less efficient.
also the compressor should be cycling on and off every 30-45 seconds with a normal charge.
best thing to do may be to have a shop recover whats in there, draw a good vacuum and refill with the proper amount.
maybe add some uv dye in case there is a leak, it can easily be traced.

Thank you. Hate to sound like a total newbie, but how can I tell on an XL7 that the compressor is cycling? Can I visibly see it or hear it in the engine bay? For my 2004, it's so "busy" and tight in there compared to my Honda Civic, maybe I'm just looking in the wrong place or not hearing for the right thing.
Edit: I will also check the fusebox again tomorrow.
