I saw this movie around 1992 but I only remember bits and pieces of it. All of what I remember played out in a skyscraper. There's demons there trying to capture this child in red clothes.

In one scene the child looks in a mirror and the mirror image starts moving on it's own and holds the child stuck to the mirror. There's also an old man outside the window pretending to be a normal window cleaning guy but is actually also a demon. When the childs parents see the demons they grab the child and try to flee. They come to the bottom floor of the skyscraper which is a parking lot. All the cars here are frozen in ice. Once they start to move among the cars they "wake up" and try to run them over.

That's all I remember. Anyone know which movie it is?
