My town car's front right window no longer works; it makes the sounds like
it wants to go down but nothing catches. Would that be a fault from the
window regulator, or would it be from the motor? The sound it makes
sounds like it normally should, just the window doesn't move. I have a
window on the back left that has the same problem, if anyone knows what's
wrong, please let me know, and thanks very much in advance.
