Hi,

Been having intermittant problems with getting it to shift into 4WD.
Am getting desperate because where I live I can't be without it.

Have had the problem off and on for a few yrs. but it always would
eventually go into 4WD.  Got worse this year so I pulled apart the
electrical  connector attached to the back of the transfer case.
There was some whitish/clear gunk in there (not dirt)...I figure it's
dielectric grease so left it alone.

I pushed the connector back together, and the next time I tried, it
went right in and out of 4WD (at least the dash light came on when it
was supposed to).

However, the next day it would not do anything when the dash button is
pushed - I don't even hear the clicks I used to hear when it was
trying to get into gear.  I pulled the connector back apart but don't
see anything wrong.

Several years ago I fooled with a test or reset button in the back of
the vehicle (in the jack storage compartment) and that seemed to help.
I know a red light comes on when I push it but there seesm to be no
rhyme or reason to when or if the red light shuts off.  It also did
not help with the shifting problem.

Any ideas?  It now seems like it's an electrical problem.  I checked
the 40A fuse in the power panel and it's OK.  Can anybody tell me what
leads to test in the connector, or have any other tips?  I'm afraid if
I take it to the dealer they will just slap a new servo into it, which
is probably pretty expensive.

Thanks.
