Window reg/motor replacement
 

Hey folks, I was wondering how hard it is to replace a pwr window regulator/motor on the drivers door of a 1990 Accord LX? When it goes up, it makes a screeching sound, and the top rear section of glass tilts towards the front of the car, leaving a slight whistling gap. I have seen some on ebay for around $40-$50, but I'm not sure if it is worth doing myself, or have a mechanic do it. Looks like there isn't a lot of room in the door panel for my *ahem* "stocky" hands to work in. Is there a way to adjust the window, or do you just have to replace the regulator? Thanks for your advice.

anybody?
