Rear driver side window won't roll down on 2003 lexus es300

I had the same issue with the passenger side rear window. I took the panel off (one screw under the window switch and one screw located behind the door handle. There is a small black cover over the screw.) I then took the motor off of the door and track system. After the track was off, I plugged the motor back into the wiring harness and tried the switch. Mine actually worked and the gear spun, if not, it will be a pricey window motor about $150-$250 depending on where you get it. Good luck! Sean

check the fuse or relay or when u press the win switch dont do or hear any,is fuse or relay but if u hear some thing when u press the win switch & no reaction on win is the motor/regulator problem..
