Jodie Perry suggests: November 30, 2014 at 9:21 pm Engaged on a 2000 Blazer and possessing a similar issue as Most are Along with the 4 wheel travel not engaging. I seemed on the web and learned that the commonest dilemma would be the transfer situation vacuum swap. After a lot of hours crawling underneath the Blazer and seeing many movies on the location, I gave up and jumped back on the web to discover what I had missed. Apparently, I found out, that if you have the 4 button four wheel push selector, you don’t Have a very vacuum switch on the transfer circumstance…..you might have the TCCM, an actuator plus a vacuum actuator swap. I checked out the actuator at first of the method plus the cable was no cost and distinct. Went ahead and lubed it up permanently evaluate in addition.
It’s doable the procedure is engaging itself. Even so, 4WD engages WITH vacuum, not without having — appropriately, maybe you have a foul vacuum swap which happens to be letting vacuum by means of when it shouldn’t. Now, why the lights are going out, that is definitely odd. I wouldn’t Assume the technique would “suggest†4WD when it wasn’t physically set there — meaning, If your 4WD system DID transpire to kick in as a result of vacuum, the TCCM would haven't received a sign to PUT the process into 4WD and therefor would not go the encoder motor, or turn on the 4WD indicator lights. If the 4WD program is kicking in because of vacuum, the one true point to get influenced could well be the front axle, and that is what is controlled through vacuum.
Given that Oct is primary fishing time on NC Outer Banking companies and 4wd is a necessity, am i able to manually set vehicle in 4 hi by pulling the cable that goes into actuator? for a temporary resolve. Again diff seems to lock but is difficult to inform around listed here, also flat and as well dry.
Hello Les — I’m about to should say no as Raymond no longer has them — yet again, I apologize for not backing them up.
ought to i be unplugging my tccm and resetting the technique soon after i change to encoder motor. I believed it absolutely was a transfer scenario proplem mainly because I believed it was binding up and never allowing teh encoder motor start out in 2wd.

About 5 minutes down the road no lights have been on, in my 4×4 activate the dash. I pushed the 2HI button and it lit suitable up.
