1 amp is definitly too much for overnight. I had an 87 Accord that had a half amp draw that took me a long time to find.

What you need to place an amp meter across the open fuse in a place that is easy to see, and then start unplugging plugs that are on that circuit untill the current draw goes away. You will want to tape the switches on the door that operate the dome lights, so you can move about the car without turning the dome lights on.

In my case, I got lucky. I had gotten into the habit of unplugging the fuse whenever I parked. I had a pasenger in the car who heard a clunk inside my driver's door when I plugged in the fuse back in (the fuse also operated the horn, so I had to plug it back in). After pulling the door apart, It turned out to be a defective switch inside a solenoid that was part of the automatic seat belt system. The solenoid was only supposed to be active if the door was open, but the swithc was bad.

A simular test might work for you two. Have one person connect and disconnect the fuse, while another person goes around inside the car listening for clicking or groaning sounds. At one amp, it is most likely a motor or solenoid. For example, A bad switch in a power window might not turn off the motor when it reaches the end of travel, causing a drain. Another posibility is a tailgate solenoid.
