I have a 99 ex and every once in a while (2 or 3 ) times a year the front drivers side window jumps out of the track. I replaced the regulator (aftermarket) around 7 or 8 years ago. It has not been in a wreck and has the original glass in it. I'm not sure if its related to the regulator, the window guides being too tight or too loose as there is somewhat of an adjustment on these window guides. Thank you
