Had a go at fixing my dodgy driver's side window today, its sticking & tilting as it gets 2/3 of the way down, adjustment & lubrication is in order. Anyway, i cant for the life of me get the door pannel off, ive pulled incredibly hard & all i can hear is like a glue peeling kind of sound, which i guess is the frame peeling off the door pannel. Anyone had this before? Or has it been glued to the door at some point?!!!
