After shutting off the engine, there is an "electric motor" noise coming from just below the battery area. On the front of the air cleaner box is a black hose going down and connecting to the thing making the noise. What is it? Thanks.
Okay, with the help of the excellent Bay 13,
Another clarification(sorry). The air pump motor is not staying on all the time. It's kicking on for about 2 seconds twice per minute. Car has now been shut off for 2 hours and it's still doing it. At this rate my battery will be dead by morning.
Hold steady. someone will know. I myself have no idea why it's coming on.

I'm thinking the problem is the relay. I disconnected the black ground wire on the air pump itself to prevent battery drain. Now the Check Engine light is on. Fortunatly here in California, if it's anything serious, the entire emissions control system is warrantied for 7 years/70,000 miles! Who knew the 97 GLT was a "TLEV" (Transitional Low-Emission Vehicle)? Thanks, as always, for your help.
