The only components inside the controller that contain a liquid are the electrolytic capacitors. One of these is part of the charge cycle timing circuit. If it leaked your car won't charge properly. One way to tell if a leaky cap is the culprit is to see if there is any white powdery residue on the PCB. Particularly around the cap that leaked. This is left behind after the electrolyte evaporates. It has a very acidic smell to it. If this is the case, you can replace the cap with one of an equal value (and that is in farads, the voltage isn't important) that is written on the side of the cap. Radio Shack and other electronic suppliers may have the cap you need. If the charging light turns red almost immediately, this may indicate a problem with the charging circuit. It could also be that the battery in your car is bad.
