Passanger Window will not work - light flashes

My ES330 passenger front window, will not go down when using the master or passenger switch. Trying the passenger switch, it blinks twice for 6-8x. Motor hums when you try to lower. What did not work: slamming door technique 3-4x (this did work for my rear side window :), fuses ok, rubber seal not stuck, holding up on the passenger switch for 10 sec then pressing it down, unplugging the switch connector and replugging, battery has not been disconnected. All other windows work from master and individual controls. Can't find what these flashes mean or what else I can try. What gets me is that I can her the motor running so it is getting power... Thx
