Ok the GEM module needs to be checked it is mounted on the fuse block. I also need you check the front actuator for proper hook up. Here is a vacuum diagram of it so you can make sure all it hooked up correctly. Now I need to know if you have a test light and a digital multi meter to test the GEM with. Get back to me. Don't forget to check the 4x4 fuse too.

Good now please check all the vacuum lines and make sure everything is routed properly and that there is no vacuum leaks anywhere. Let me know what you find and we will go to the next step.

Well if it is working then we can't find the problem as the problem is not there now. You may have found a loose connection when you where checking the wiring. If there is any more problems let me know and we will work on it.
