I just bought a T type, one of the knobs on the driver side power window switch is broken. Does any one know how to pull these things out? i started to unclip the panneling on the door and felt up there, it seems as if it should unclip out w/o having to remove the panneling. I also got kinda stuck on pulling out the pannel, does the pull strap have some fasteners hidden underneith it? thanks for the help.
