1997 Explorer XLT - 4WD Not Engaging

[wcsd106]

Hello All.

Now that I have my 1997 explorer XLT starting reliably, it is time to move on to the second item on my priorities list... Getting the four wheel drive to engage.

Here's what I have so far.

• With the front tires jacked up off the ground, I was able to turn both wheel and observed the front driveshaft turning.
  
• Prior to starting the vehicle, the 4x4 and 4LO lights illuminate during the lamp test.
• Turning the control trac switch from 4Auto to 4HIGH or 4LOW prior to starting the engine or while the engine is running has no effect, whether the vehicle is in park or neutral.
  
• Regardless of switch position, no clicks or indicator lights are observed
• All fuses in the drivers side panel and the power distribution box test good with a multimeter. I did a visual inspection of all fuses related to 4wd for good measure.

This early in the game, I would expect an electrical issue over a mechanical one, but I'd like a good nudge in the right direction as far as troubleshooting.

I've been doing some reading and will continue to do so while I await responses. Thanks again for all your help.

After doing a little more reading, here are the next steps I'm planning to take:

• Remove the radio and bezel and test the 4wd switch using a multimeter
• If the switch tests good, then with the engine running and the selector to 4HIGH I will check the brown wire for 12v.
