I want to diagnose why my front wheel's are NOT engaging when I shift into 4H or 4L. I took the skid plate off protecting the actuators and sprayed carb cleaner to get a good look and all hoses were fine and the 2 electrical plug-ins were fastened. I'm hoping to get lucky and I am trying to locate any fuses or relays that I can check. I'm afraid it's one of those actuators and I couldn't see how they unplugged....... I am blind in the right eye. Any advice is appreciated..... I have no way to check voltages or vacuum......

You should be able to feel vacuum with your finger, there should be a VSV (vacuum switching valve on the fire wall about middle of the engine bay, check this as well,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
