Hey, i have an 07 SI sedan as well, and my rear driver side door is experiencing the same issue.Thanks for the great write up.
I just used your guide to change the rear drivers side lock actuator in my '07 Si. It was virtually identical to your front door guide only there was no window bracket to remove. The window bracket is stationary and the actuator easily slides out from underneath it on the rear door. You are not kidding about needing the strength of Hercules to get the door linkage free from that damn plastic clip. I just knew that I was about to break something. Things were popping, creaking and cracking when I was tugging on that linkage. Once it broke free the clip went flying, took me another 5 min to find that stupid thing. Took me a total of 1 hr 15 min from start to finish to change out the actuator with the assistance of your guide, fairly easy job.
is the part # for that also 72150-SNA-A14?
