    Hi all,

    I'm hoping for some advice. My 4x4 stopped working and I don't know why. I checked the fuses under the hood;
    #35 20A mini fuse 4x4 Module
    #43 20A cartridge fuse 4x4 Module motor
    #75 5A mini 4x4 IWE solenoid

    and all are fine.

    I do hear a clicking noise coming from the pass side when I engage 4L. And I do get the light on the dash saying its engaged. But when turning to 4H and 4x4 Auto, no clicking from pass side and no lights. It does say, "4x4 Shift in progress" but then goes away and no tell tale message saying it's engaged.

    I do have 220,000 mile on her and outside of patching the rockers and some paint peeling from the hood/ tailgate, it runs and looks like a new vehicle. Can someone please help?

    Hey there so i experienced the same exact issue you are having. 4LO engaged perfectly but i got no 4A or 4H when i experienced the issue. No indication on the dash. So originally the switch was suspected on mine and did that, but the problem came back a month back. So i pulled my radio and center trim on the dash out and pushed in on the connector behind the switch, i then got under the truck and went over all the connections on the the transfer case. Got in and walla all the functions have been working properly again, it was a loose connection somewhere.

    My issues came back, looks like I’m having the dealer put in a new transfer case..... not good news.

    Well,

    I think I narrowed it down to either the switch on the dash or the transfer case motor. Since I used 4L last night, I ruled out bad fuses and IWE. Hoping it's the cheaper of the two.

    After DAYS at the dealer they went over and cleaned every connection and said a “diverter valve” was bad. I’m thinking that’s the vacuum solonoids but not sure, but I’m bringing it back Tuesday to get that replaced, they said they have it so the 4WD will work temporary but this weekend the dash stopped displaying it and I lost it again so I’m not convinced that’s the issue, let me know if you get your resolved first because we’ve got the same symptoms. Since I’ve lost mine again I still get 4Low like before, but no auto or high yet again.
