I'd hate to replace the more expensive motor, only to find out that the cheaper switch was the culprit.
As long as it's not frozen shut, I would start by checking the wiring that runs from the up/down switch to the window motor. Push and pull on the wires to verify that they are in place and making contact with where they are supposed to go. Then inspect the wires that lead into the door. If everything looks good, then it's time to get out the test light to determine if the problem is the switch or the motor. Then replace the faulty part.
Or, a different route, find another up/down switch in a junkyard or eBay for really cheap and swap them out. If it still continues to do it, then you know it's not the switch.
Maybe you'll get lucky and find a loose ground wire in there somewhere.
