My remote works on all but my uplight. It works fine with the downlight and the fan itself. Already tried DIP switches.

Welcome to FixYa!

The whole system of this kind of fan is integrated in one PC Board (PCB). Your problem concerns only a portion of the components of the PCB. You need a tester, soldering iron, soldering lead and must be able to know how to use the soldering iron and must be able to identify capacitors/resistors.

My best advise is to replace the whole PCB since it will require you a tremendous work if you are not knowledgeable about the things I mentioned, and needless to say, the components are hard to find than the ready made PCB.

You can visit this site http://www.eceilingfans.com/hampton_bay_ceiling_fans.html and give them a call to order for your PCB. They have available PC Boards for all hamptom bay ceiling fans.

You can contact them in these numbers: Phone 979-553-3260 Fax 979-553-3391
Just provide them with the model number of your fan (AC-552AL) and order for it's PCB.
