Hello everyone new here from pa. I just bought my first Lexus ES300 196000 miles in it. The drivers side window and back rear passenger window don’t go up or down. The passenger side window works and the rear drivers side window works all from the master switch. Master switch I mean drivers switch. I bought a new switch online but then none of it worked. Any ideas on what could be wrong and how I can fix it. Thanks everyone. I love the car bought it to run errands. I’m getting 24.6 mpg.
