It seems they have to move forward a couple of feet before the 4 wheel drive will engage. This is a problem that occurs frequently with this system. Does anybody have a picture or diagram of where this vacuum reconnects to??? I picked up a 99' 2500 for a steal, but I've always been skeptical of the push button 4x4 and electronics failing in a storm. Transfer case switch is electric. The butto … n can be purchased from a Nissan dealer for couple of dollars.
No problem until a week or so ago. If you have power door locks push a wedge into the top corner of the door - two screw drivers work great or a tapered block of wood. I have checked the transfer case and the panel light fuses. Does not work with '99+ Ford axles. There is possible the … switch could be bad or the 4x4 shift module located behind passenger side kick panel. Back on the road however the problem is consistent.
Not everything has a solid explanation. Does not work with '99+ Ford axles. Being both cheap and inquisitive, I wanted to investigate further, and I will provide a more in-depth answer. I would not worry or waste time with checking for vacuum leaks or the vacuum actuator, as the book does not point to that direction at all. Posi-Lok makes some systems, not sure if they make one for the expedition, but I am sure it could be adapted to work. Am I safe to assume that I'm correctly diagnosing this issue? The voltage should remain near 1.
Also is the module on the Transfer case itself? I pulled the fuse and disconnected the battery. I bought this for a 2002 Chevy Suburban. I think I'll leave the Burb alone, as when my wife is driving, I like that she doesn't have to fool with anything, just throw it in 4x4 with a switch. Always downhill The thing is you would have to get some kind of mechanical connection to engage the front axle with that swap. Only time I use 4-Low is those really scary downhills.
I have a guy who builds custom four wheel drive set ups that wants to look at it Monday. Thanks for all the help, after checking to make sure both circuits from the module to the transfer case motor were not open I got more confused because I had no problems there. It was a poor design. Inspected dash switch, nothing obvious and it does function. Is that 03 supposed to be 93? Thanks ahead of time for any ideas.
Sorry this is my first post here but I have to get it out of the way. Better off just trying to turn around then to try to go forward again. If more than 1 code is stored, the first code will blink, then there will be a 3 second delay, then the next code will blink. . Is there something that splashed on the switch panel, and perhaps is causing it to stick.
Not the the 3 hose vacuum switch seen all over the inter web. Adding in any of our gear reduction systems is relatively easy, give use a call to discuss those options. Back close to the switch by hand and check for a glitch. The site is fully functional and ad free! It should not require a great amount of force. Saved me a lot of money and I appreciate it. Just install a manual transfer case and floor shifter. It sounds like a fault with the switch, and it changes range, because park or neutral and 0 speed, meets the criteria for it to shift.
I used a lamp based test light to be safe. Changed it and sound was gone and shifted even easier. Got locked out of my van, and couldn't open the doors even though I could reach through the window and push the lock button in front. The use of a good scanner could help pinpoint the trouble. And crash into the car that cut you off, saying 'I wish I had it in 4x4' 4wd, the front tires will continue to turn, until you hit the brakes hard enough to lock up all 4 tires. Count the number of blinks before the 3 second delay to determine the code.
We see you haven't yet. There are 2 things you will need to do. You were going too slow up that hill, depending on each revolution of tire to grab. We later discovered the vehicle's history and realized it needed a lot of work before we could drive it. Buy the new wiring harness that goes from the transfer case to fuse box under the hood. I couldn't tell because the electronic axle switch was bad as well so the lights on the 3 button 4x4 control all looked perfect, e.
