Hi everybody.i have a 93 940 sedan with a cracked back glass from top to bottom.first i am wondering if the defrost will still work in this case.second i would like some instructions on removing this back glass.i have done it on a 740 but this one seems different especially trying to remove the trim around the glass.a new glass is $325.i was thinking of getting one from the junkyard to save money.if somebody has done this,i would appreciate all help.thankyou in advance and have a good day.charles.
