97 expedition - I am able to turn the 4x4 switch to AWD, 4H or 4L, th einidator light comes on, but the 4 wheel drive does not engage. I detect no clunking sound when attempting to engage and I hear no grinding of gears. Where do I start to troubleshoot?
The first thing i would check on any 4x4 AWD is to see if the vacume lines
were conected to the transfor case and getting vacume when engaded i have found this to be the
most commen answer
I had the same problem. I talked to the local Ford dealer and they recommended changing the transfer case motor. I ordered one for around $70 and installed it. Problem fixed. I hope this helps.
I have the same problem can't figured it out although when i turn the knob to AWD the light on dash just flashes. the 4x4 H and 4x4 L light on dash stays on.if u have found out anything please let me know or e mail me at [email protected] Thanks Don
