The light in the insterment cluster for 4 wheel lock dosen't come on when the the shifter on the floor is put into 4lo or 4hi. Could this be the transfer case position sensor. If that is possible where is it located and hopw do you test it?

Do you

I think you are correct. THere is a switch on the top (of all places) of the transfer case that turns the light in. They go bad. The part just unbolts, but it is a tight space.

Here is what I was able to find. I believe you need to locate the mode sensor. Confirm that with the parts store. NOTE: This picture is for a 6 cylinder auto trans.
