Side Mirror Actuator Correct Part # ?

[cbohannon25]

I'm getting around to fixing the side mirrors on my 07 tahoe and need a little help. Its an 07 LT with power fold and I would assume memory but since I bought the car in 2022 they have never worked. The power fold function on both is broken but I have a good grasp on that fix. What i'm struggling with is the glass actuator on both sides is broken as well and there are so many options i'm not sure which is the correct one. I would assume it's a power fold but there is a 1st design and 2nd design. Also with the prices of these actuators and the glass (my driver side glass is cracked) it seems it may be a better deal to buy a used mirror and scavenge parts off that? Just wanted some advice

Also was curious if anyone has ever repaired these little actuators? I saw somone on ebay was selling the motors and the gears but i tried to split mine to find the issue and had no luck.
