How do you replace the window regulator on a Toyota Previa?

Answer 1

I drove one about 600k. They do not usually go bad. Once the door panel is removed, there is about 4 bolts holding an "x" type assembly(heavy metal old style regulator used by many manufacturers, including GM). Motor itself can fail, and is attached by a couple of screws, and is in a black plastic enclosure(replace the whole plastic assembly). If you live in the snow belt, and you try to lower the window when it is still stuck to the rubber moulding, it will strip out a few teeth, and will not go all the way up. Usually about an inch still open. One cure for this is to remove the "x" assembly, and take it to a weld shop. They can braze you a couple of spot drops in place of missing teeth. Basically a couple of drops of weld. You can then file them down to look like the rest of the teeth on the assembly. Grease all the teeth real well, and you will be in good shape for many years. More than likely, your problem is the latter.
