My 08 has the same problem; looking for a solution.

Great write up. I recently completed this mod and it works great. Please note, I used a different harness that required NO modifications. I have a 08 LT silverado and found a harness that was a direct plug-in. The part number used was 25776048.

My driver side acuator just went out on my 2008. I like your method compulynx. I may be giving your method a shot on my truck. You said there are more than two wires going to the stock actuator. If this is the case then what is the fuction of the smaller gauge wires that do not power the acuator? Did you keep the smaller wires hooked up to the old actuator to complete the cirucit?

Does anyone have the part number? Can the actuator be purchased at a auto parts store or is it dealer only part. My truck is ready for a new actuator, it only locks and unlocks half way.
