Quattroisti! I have an 86 coupe GT with a dead driver window. We have had some cold weather in DC lately and I noticed that it didn't go when it was extreme. (c. 5'f.) When it warmed up it worked fine. Yet, when I tried it yesterday, it did not go down at all. (and yesterday was a relative warm day: 50' f. Any suggestions as to what has happened? Thanks, Kevin
