If you 1st remove the window switch panel, it makes it A LOT easier to then remove the door panel as you outlined. ( there is fantastic write-up with pictures included on this forum. You will be unclipping the master window harness & then the mirror harness. You can actually see to unclip them.)

The master switch seems to be the root of a lot of different window issues. Glad you finally got a resolution ....... Just a side note*** seems the mechanic should be able hook-up to the computer and an error code #1windowprob should show up with changing the Master Switch as the solution, lol or if all else fails - Change THE Master Switch!!! It's the brain of all window functions
