Your windows are `92..you need new weatherstripping. you will most likely have sash and frame w/s..look closely at how flat and compressed it is,get marvin leaf and bulb.it works on 90% of the windows out there..if your gonna DIY it spend the extra money and replace the upper and lower hinges.their fairly inexpensive if you know where to look..and if ya do all that your windows will be "Tuned Up"..oh and by the way the ice is happening because the cold air and warm are is meeting on the sash...because of the W/S
PSS... the windows pictures are of `90`s series scherer/farnorth windows..I can tell from the boot and the operator cover
