I believe the answer is:

air-con

I'm a little stuck... Click here to teach me more about this clue!

'the cooler' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'show criminal' is the wordplay.
I cannot quite understand how this works, but
'show' could be 'air' (both can mean broadcast) and 'air' is present in the answer.
'criminal' could be 'con' (abbreviation for 'convict') and 'con' is located in the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).

'in' acts as a link.
