    4x4 not engaging. No light on dashboard, no sound of transfer case switching to 4 low

    After further troubleshooting I found that IWE solenoid was switching properly and sending vacuum properly to front hubs. I ended up getting on JustAsk and speaking with a ford tech and was advised to have a mechanic check for codes and found a bunch of codes relating to the transfer case...

    4x4 not engaging. No light on dashboard, no sound of transfer case switching to 4 low

    I found a video online that showed how the 4x4 hub system works. I tested and everything is working properly at the solenoid so I know that the 4wd module, switch, and solenoid are working. I can't find a wiring diagram so I will go to Just Ask for more support.

    Need circuit diagram for 4 wheel drive - 2004 Expedition Eddie Bauer 5.4L

    If anyone has a circuit diagram so I can figure out why my 4x4 is not working I would appreciate it. 4x4 is not engaging and neither the 4 high or 4 low lights will come on in the instrument cluster. Not getting power somewhere in the chain. Thanks in advance!

    4x4 not engaging. No light on dashboard, no sound of transfer case switching to 4 low

    I haven't analyzed the fuses yet, but burnt fuses imply other problems. I'm not familiar with the issues youve suggested but I will check those first and foremost Thank you, much appreciated :) Also the under-boob or your image is epic... party...

    4x4 not engaging. No light on dashboard, no sound of transfer case switching to 4 low

    What is the signal chain? Can I check to see if voltage is being applied to a specific actuator motor? I don't have the proper documentation. Is the main computer telling the transfer case to engage? What is the signal path for the 4x4 lights on the dashboard? Trying to find out what I need to...

    4x4 not engaging. No light on dashboard, no sound of transfer case switching to 4 low

    I recently had my transfer case replaced on my 04 eddie bauer with a used unit (mechanic said it was stuck in 4 high) and this apparently damaged the transmission so as soon as I got it home I had to take it to a transmission shop for a rebuild. I tried to engage 4x4 yesterday and nothing...

    When you switch to 4x4 you will get an amber light on the dashboard showing 4x4 high or 4x4 low.

    Needing an engine diagram of air intake system of 04 5.4L or advice

    Makes sense. My goal initially was just to find a paper filter to replace the one I have but for some reason, the one I have is apparently the only one that doesn't have a paper filter equivalent. It's a bummer.

    Needing an engine diagram of air intake system of 04 5.4L or advice

    Does anyone know what that adapter piece is called or where to find it? I checked all of them on the website and couldn't find a paper one like mine. Yeah I wouldn't trust removing the oil. I really wouldn't trust the engineering behind the air intake system itself either as compared with...

    Needing an engine diagram of air intake system of 04 5.4L or advice

    Not a problem! I used to be a fan of K&N as well. I'll be putting my K&N system on ebay as soon as it's off.

    Needing an engine diagram of air intake system of 04 5.4L or advice

    Here's one: https://www.nicoclub.com/archives/kn-vs-oem-filter.html "Compared to the AC, the K&N “plugged up” nearly 3 times faster, passed 18 times more dirt and captured 37% less dirt. See the data tables for a complete summary of these comparisons." "The other filters, most notably the...

    Needing an engine diagram of air intake system of 04 5.4L or advice

    I do have the IAC valve. What I'm missing is the little coupler/adapter that goes on the end of the IAC hose and allows the hose to join into the Air Intake right in front of the throttle body. You have a zip tie on the piece that I'm missing.

    Needing an engine diagram of air intake system of 04 5.4L or advice

    I ordered the parts from a salvage yard online as I couldn't find what I needed locally unfortunately. I'm not a fan of K&N filters from my research into people's detailed experiments with their filtration ability and already have the OEM parts at this point. I had considered buying second...

    Needing an engine diagram of air intake system of 04 5.4L or advice

    Yes! The IAC valve. I didn't know what it was. Thank you for that picture, I can see exactly what I'm missing in your picture and it is the little adapter / fitting at the end of the top hose. I have the tube assembly but not the adapter. Unfortunately I have been unable to locate a dry filter...

    Needing an engine diagram of air intake system of 04 5.4L or advice

    When I bought my 04 EB 4x4 expy it came with an aftermarket K&N air induction system on it and I'm not fond of oiling and dealing with the K&N filters at all. I bought an OEM intake system from a salvage yard but am having an issue due to a piece missing apparently. There are 2 hoses that attach...

    Left blinker not working on 4 or 7 wire trailer plug

    Parking lights, right stop/blinker is working fine on both trailer plugs, only the left stop/blinker is not getting any voltage at either plug. :( Are you saying there is a separate fuse for the left and right blinker on the trailer plugs? I did not see that. I will double check in my manual...

    Considering a 2004 Expedition Eddie Bauer

    The 04s were the last year they used the 2 valve engines that didn't have the cam phasers and spark plugs that break when removing them.

    Left blinker not working on 4 or 7 wire trailer plug

    2004 Eddie Bauer 5.4L 4x4 Blinkers on my Expedition work fine, and all of the other trailer connector wires have voltage and are working, I just don't have any voltage on the left stop/blinker wire on either the 4 or the 7 wire connector. I have wiring diagrams, anyone had this issue before...

    How to replace the positive battery terminal on 1st gen Expedition (2002) without new cables

    Nice! "Two bolts holding down the pos clamp bridge". You meant on a new terminal end? Didn't see you mention a new one. Good solution too!
