I recently did that on my AT AS ES DCT to replace a broken turn signal from a drop. The service manual provides quite a few steps to remove the front turn signals.
Set aside about 4 hours and exercise a lot of patience. Helps to have a few extra push pins as some are likely to break upon removal.
Big picture from service manual; numbers are the pages from the service manual; Indentations below indicate dependencies on item above.
To Remove front turn signal (2-15):
Remove front side cowl (2-13)
Remove inner panel cover (2-17)
Remove front center cowl (2-12)
Remove windscreen (2-18)
Remove middle cowl (2-7)
Remove tank front cover (2-6)
You really should purchase the service manual before doing this.
Nurse all covers off softly, otherwise breakage may occur.
This is a bit of a painful exercise, but not too bad once you've gone through it.
Upon reassembly, I used a small amount of silicon grease on the cover bosses so that they would slide into the grommets easily.
Best of luck!
