Yesterday, bought a 10 oz. can of Johnsens Silicon Lubricant at Kmart for $2.99, plus tax.
Sprayed some of the clear liquid, liberally, on both window tracks. It dried within seconds and remained clear. Tried raising each window and to my utter amazement, the windows worked like when I drove my then brand new '99 Ironman off the dealership lot. This miracle liquid was from the window seals fountain of youth. One of its applications, as stated on the can's instructions, "Lubricates and prolongs the life of weather stripping on hoods, trunk lids, doors and windows."
Couple years ago, paid an auto shop $1,200 to fix the window binding problem. They installed new hardware and applied silicon grease, but the binding problem persisted. Sure wish I'd found this can of magic before coughing up over a grand.
