Bro,
TC and other workshop normally change the whole assy.
As for the mirror, i think it come with motor.
So i guess it cost more.
Just to share, i just wack my right tail lamp today.
Only the cover crack, the electical signal perfectly ok.
Call up TC, and was quoted about $210 for the lamp assy and $70 for labour.
In the end i go ubi find don have, then finally my friend manage to get a 2nd hand original tail lamp( last pc ) in Sin ming.
At $40 include install.
I was so heng man.
Faster drive down and get it change.
