Hello all. I'm hoping I have come to the right place. I bought a new to me 2001 Expedition Eddie Bauer a few days ago. I knew it would have problems going into it but now I am getting in a little over my head. So I will start at the beginning and go from there.
I got the vehicle home from the purchase and pulled the engine codes. I got P0357, P0442, P0171, P0174, and P0307. I did my research on them and looked into what would be needed. I knew the 442 was most likely the gas gap, especially since the cap that it currently had didn't correctly click. I was right and a new gas cap fixed that problem. The P0171 and P0174 were also an easy fix. I figured it was most likely a dirty MAF sensor and I turned out to be right. While I was at the parts store buying the cleaner, I picked up an air filter too. I figured it was just safer to change the filter out and start my own routine. Turns out the codes were created because there was no filter and so that is why the MAF sensor was dirty. The P0357 and P0307 were both about cylinder #7 having a misfire issue. I lucked out here and only had to replace the boot for 5 bucks. So now all of my engine codes are cleared. Yay, go me!!!!
I have also replaced the engine oil, added some transmission fluid as it was low, replaced the fuel filter, and changed out the differential fluid. Next on my list is a transfer case fluid change.
So here are the major issues.
I can't select a 4x4 mode without blowing the fuse for my backlight on the instrument panel.
Putting the truck into any mode other than 4H results in 4x4 light being on but then not being able to drive forward.
Having truck in 4H mode results in being able to reverse but not more than at an idle speed, however the truck will drive forward just fine. The 4x4 light does not currently come on in this mode.
In A4WD it reverses better, but slips while trying to go forward.
I am assuming spinning the knob all the way to the left is A4WD and to the right is 4L. I don't actually know as I am missing the knob and have to use some pliers to turn it.
The wife noticed while I was cycling through the gears while filling the trans fluid that switching gears had a loud clunk sound, like a binding sound. Almost like when a brake pad sticks.
The sun roof worked in vent mode until I tried to make it open up all the way and it sounded like something came off the tracks. I think the motor works fine but something is jammed and stopping it from opening.
The very back passenger window motor works to open up and vent but not if you constantly try and use it. You have to give it a minute to recover before it will work again. The driver side motor doesn't do anything at all.
The power side mirrors work for side to side and down but won't go up. If you push up on the joystick it makes it go out away from the car.
The power drivers seat can go up and down and backwards but won't go forward anymore than where it is at. It feels like it should go forward a lot more.
The power pedals don't move forward or backward but you can hear the motor trying to do something.
The AC doesn't work but I haven't even gotten into messing with that one. The previous owners said a recharge would last about 5 months. I am guessing there is a leak somewhere that I will have to find.
The gear shift can't go far enough down to reach first gear. I run out of room while moving through the gears. I named out the gears it was in three times to make sure I wasn't missing something.
So this is my investment and I would appreciate any help I can get trying to get it all going in the right direction. The biggest concern right now is getting the 4x4 modes to work right and for it to drive properly all the time. I don't know if it is a transmission issue or transfer case issue or if it could be as easy as the transfer case motor. This is an entirely knew world to me as it is my first truck and first 4x4 vehicle. I'm not afraid to dive in and work on it myself. I bought the chilton guide to help out with that. If it turns out that it is a serious trans or transfer case issue, then I will need to save up some money to fix it but I could totally spend my free time fixing any electrical issues it may have.
Any help is much appreciated and I look forward to getting to know you all.
Thanks.
