well it's the driver's side...which is electric, so im still stuck.
i've tried pulling on mine like hell and it just dont wanna come off. i havent the slightest clue. I'm thinking about trying to do it on the passenger side first, that way if i break it, i wont be sol until i order a new part.
push the seat cover down/in until you can see the bottom of the knob; got a set screw in it maybe?
