For the first problem you probably need a new window regulator - you've probably got a stripped tooth. These are about $80-90 and can be a do it yourself project if you have either skill or determination. On the check engine light you need to get the fault code. On your car you can do this yourself by pushing a little black button on the computer diagnostic module under the hood. Do a search of the archives for things like "check engine light" and "fault codes" - there's a whole bunch of stuff there. It's not urgent but there's something wrong that's going to need some attention.
