2001 ZR2 4wd won't engage

Asked by Nov 15, 2014 at 09:47 PM about the 2001 Chevrolet Blazer LS 2-Door 4WD

Question type: Maintenance & Repair

New parts list
-new encoder motor
-original kick panel modual and a junkyard
one neither fixed thw problem.
-new dash switch (3 button)

With motor running and in neutral push the
4hI button and the 2hi light stays on while
the 4hi light blinks a series of times and u
can hear the modual in the kick panel
clicking but it stays in 2hi. Took the battery
out and the tray and the vacuum boot seem
to all be in tact, no tears. Even pulled the
diaphragm back and zip tied and tried it and
still just binking. Please help.

Is the transfer case full of fluid?

Lol honestly haven't checked, why would that cause that ?


Because you've looked at just about everything else there is to look at on an s-10 4x4. I'm just wondering if its low on fluid that could be your problem.
