Drivers side window will not open...roof won't either

After backing the car into a post and setting of the roll bar last year I have not been able to raise the soft top and the roll bar light flashes continuously. I was able to "park" the roll bar by holding the switch till I heard a click and was able to lower the bar.
Been ok since then but now tgh drivers window will not lower.
I tested the motor by putting 12v directly to it and it works.
The codes I get when scanning it are :
123: EDW convenience micro switch door L S86 R S87sl trunk S88sl
101: front power window motor hall effect sensor not synchronized
99: Left front power window motor hall effect sensor
Plus the following codes with no description: 134 103
Does this sound like a micro switch problem on the DS window?
Where is the Hall effect sensor on that door?
How are they replaced?

Thanks for the help....this soft top has been nothing but problems.

The first sort you provided is excellent, but I have never experienced some of the codes, with that said, please understand my basic approach is sync the windows.
The Halls effect sensor is a rotation counter, on the window motor (??). the process is covered in your owners manual. It is like the roll bar button push thing. The 600 I have now is older than yours and does not have the Hall system.
Run the motors for both windows at the same time in the same direction to get the rotation counter sensing the same data. If memory serves, it takes several full ride to get the sync. So if one window motor won't move then maybe hand turning would be a way to get the sensor to get in phase???
What model year do you have? and where in the world are you
