Can you ID these 98 Tracker parts?

The small box on the left hanging from beneath the glove box is the a/c amplifier.  Assuming car is equipped with a/c?  Its a mini computer of sorts that controls your air conditioning.  Expensive to preplace if you can find.  $400-$600.  Bypassed mine with a switch on dash.  But in doing so compressor runs constant when on ..does not "cycle"  Had this go bad on on 2 trackers and 2 sidekicks
