Re: Weird 4x4 issue.
Here's an excerpt from the article I found:
2. If all the fuses are good, the next step is to run the 4x4 module self diagnostic. The 4x4 module is located behind the driver’s side rear jump seat on super-cab models, but as far as the other locations I don’t really know. This module will have three connectors going to it – one will be a pig tail, the other two will be located on the right side of it (side towards the front of the truck). These two connectors must be removed to diagnose the module.
With the key in the off position, remove these two connectors from the module.
Next, turn the key on with the engine off. On top of the module is a white rectangular button located next to a red LED….push the button and watch the LED.
a. If it flashes, this indicates the module is working properly. Go to step 3.
b. If it lights up and stays on, it indicates that the module is likely bad.
c. If nothing happens, it means the module is either bad, or has no ground/power.
In either of these instances (b or c) power and ground should be verified before scrapping a 4x4 module.
I went thru it and it helped. I'm not good with anything that sparks so thankfully I only had to go up to this step and my module was ok.
Good luck with it.
