As of the December 4, 2015 patch, the fan is now appearing in the search and in build mode. This is now working in my game.
Here's a thread for the blueberry thing: http://forums.thesims.com/en_US/discussion/825010/blueberries
Do you have the item on the police lot ?
tested this out for the OP and (no mods or CC) even did a repair game in Origin just in case and i also started a new game with new Sims in the unlockable rooms i don't see the fan in the room and i used the bb.showhiddenobjects went through debug by pack then all of debug no fan and yet it is at the police station however i had the new Sim join the police force joined him at work i used the cheat bb.enablefreebuild used the eyedropper to clone the fan and it showed up in police station items then switched control to a Sim at home used the cheats testingcheats and buydebug and the fan does not show up
