I'm no expert by any means; I can just tell you what I did to get my FWD running again. I have a 2000 Chevy Silverado, Extended Cab, and Long Bed with 180,000 miles. I bought the truck about one an a half years ago or so, and the FWD didn't work back then. So, last summer I started working on it. I did just as you have done, and looked it up on the internet. I went to a number of different sights hopping I could find a quick fix and save a lot of money. After reading I found things I could do with the help of youtube videos. I did the following:

1. Looked for a blown fuse. I only found one fuse that said FWD, and it was the one on the inside of the cab. Looked good. So that wasn't it.

2. Changed the selector switch. You know the push button thing, in the cab. This wasn't it either.

3. Changed the actuator. Nope not it.

By this time I was not too happy; therefore, I did the unthinkable, I took it to the Chevy Dealer. After all having a FWD truck, but the FWD doesn't work, just don't seem right. Kinda got my feelings hurt when they said "$100.00 dollars an hour." No thanks. So, I did without the FWD last winter. Luckily, it wasn't a bad winter.

So, before this winter, I was bound and determined to get it working come hell or high water the things gona work. After replacing all the parts last year and it still didn't work, I knew it had to be electrical.

I found a web site that has all the electrical information for my truck or any vehicle for that matter. It's called Granted, I did have to pay like $25.00 for a year, but I did it anyway. And, low an behold, there is a fuse. It's not labeled FWD, its labeled ATC. (Automatic Transfer Case) It's under the hood with all the other fuses. So, I don't know what the actual problem was or how the fuse got blown, all I know is after doing all the steps above and replacing this fuse, it's working. I just had to try them all, I guess. Good Luck!!! And thanks everyone that posted on here. IT WORKED. I don't know which one done it, and don't care. I got my FWD back.

If your 4WD switch hasn't been replaced, it needs to be. There was a TSB on the early versions of this switch. The new part #15709327 Transfer Case Shift Control Switch
should solve your problem. If your switch has been replaced, then you will need to look at the ATC module, either re-program, or replace.

I have a 1998 Ford Expedition 4x4 4.6L. Put it in 4wheel drive and it won't disengage. I've pulled all the fuses associated with the 4x4, tried many different approaches of being in neutral, switching...

If that's a model where you push a "4x4" button to engage it then it's
probably a defective motor that engages/disengages your transmission
from the transfer case. It's bolted onto the transfer case just like a
starter is bolted. Yes, the 4x4 light will sometimes mislead you by
going on or off when you push the button.
Ford charges an arm and leg for their replacement but an aftermarket
one runs about $90 from Make sure you get any electrical
documentation for this motor to show you how to set up the connections
for your particular vehicle......Ray
