At start-up my wife's 2001 Intrigue makes a very loud noise, which sounds like a motor or pump running. This lasts until the fast idle kicks down and then it goes away. It used to be a whine, now it has progessed to a scream or high growl and when it goes away it sounds as if it's hanging up or something, then it's gone. The sound seems to be coming from the drivers side front engine compartment, under the airbox perhaps, but I'm not sure if there's a pump or motor of any kind underneath the airbox area. It's getting really annoying and I haven't really torn into it yet - just wondering if anyone knows of a pump or motor that runs on start-up?
