Also see this.. They also say never put power to the actuator without it being hooked up.......
+1 on that one. I made that mistake and had to take mine apart and move the worm gear enough times for it to be within the operating range and then recalibrate the system.

I had read earlier that grease migrates onto the contacts of the actuator, I pulled mine off and there was grease on the contacts and the area where the contact makes contact to the p.c. board. I cleaned the grease with q-tips and alcohol and put it back on and it is working fine now, just be careful to note where the notch is located on the outside cover before you pull it apart. since I have a 2004 GMC Sierra Denali I have the center console so it was a booger to get at the actuator, but I finally got it out. my actuator snapped together and some are held together with screws. since I imported my truck to Dubai where temperatures are triple digits from June through October having a cooling ac is a must. my Denali came with the quadrasteer options and does great in the narrow roads in urban Dubai and surrounding suburbs. it you have enough knowhow to remove it then you can save money by just cleaning the contacts, also DO NOT Operate this unit once removed it is calibrated so be careful to either mark you gears or take a photo to ensure you put them back in the same location, you only have to remove 2 gears the rest remain in place. good luck.

(1) added larger radiator
(2) added independent B & M fan assisted Transmission and Engine Oil Coolers
(3) added dual electric fans on the radiator.
with temperatures well up into the 130 degree F range, this is imperative.
hope these tips help you out.
