98 Navi will not switch into 4H or Lo range

[bhickmott]

My 98 Navigator will not switch into 4 Hign or Low Range.

The 2 High and A4WD work fine. When I switch to 4H I can hear the relay inside the dash click 6 times then the A4WD indicator light comes on. The same 6 thing happens when I swith into 4Low, relay clicks 6 times and the A4WD light comes on (yes, I have tranny in neutral and my foot on the brake while trying to switch into low range). If you drive it with switch in the 4H position the A4WD function works for a while then the light goes out and it switches back 2H. No problem with switch in the A4WD position. 4 wheel drive kicks in when the system senses wheel slippage.

Anyone have any suggestions ?

Turned out to be the Transfer case shift motor was seized up solid. Looks like it just rusted out. It's a pretty simple replcement item. Although you do have transfer several connector pins from the old connector to the new connector on the replacement motor. So it's not a straight bolt in replacement.

Anyways, the folks at www.justanswer.com were great in helping me diagnose the problem. This is a great site for helping you with any Ford product problem. They have 10 to 20 Ford mechanics on-line to respond to any question. Check them out .... I'm sure you'll be impressed
