Heat Actuator replacement instructions needed?

There is a clicking noise that appears to be coming from the console that rests between the 2 front seats. In searching YouTube, it seems like the actuator has broken a gear/tooth and that is what is making the noise. When I adjust the heat to the rear control it does appear to affect the sound, which makes me think that is the issue. When I took it into a local shop, they also thought it was the actuator, but I was told that the actuator was actually behind the front panel and that it would take 6 hours of work to disassemble and reassemble to get to the part. I would like to take these parts apart myself but got stuck rather quickly when I could not figure out how to remove some pieces without breaking them. My questions are. 1 - Is there a way to find out where the actuator actually is located? 2 - Is there a video online that would walk me through taking the car apart to access that part (along with listing any special tools needed). Thanks so much!
