Jodie Perry says: November thirty, 2014 at nine:21 pm Engaged on a 2000 Blazer and possessing the exact same challenge as Most are Along with the four wheel push not participating. I seemed on the internet and found out that the most typical issue could be the transfer case vacuum switch. Just after lots of hours crawling underneath the Blazer and observing quite a few videos over the location, I gave up and jumped again on the internet to view what I'd skipped. Apparently, I learned, that When you've got the four button 4 wheel generate selector, you don’t Have a very vacuum turn on the transfer situation…..you've got the TCCM, an actuator plus a vacuum actuator swap. I checked out the actuator in the beginning of the method as well as cable was totally free and very clear. Went in advance and lubed it up for good evaluate likewise.
I’m not thoroughly absolutely sure what leads to the lights to simply blink and then not go into gear. The first time I set the Blazer in 4Hi this winter, it did just that…. I had to set it in neutral for it to go into 4Hi. Considering the fact that then, it'll shift on-the-fly. Why? I don’t know. There needs to be sensors either in the TC or perhaps the encoder motor to Allow it know when it has achieved it’s intended method… I’d suspect it’s A part of the encoder motor, but I’m just guessing.
Considering the fact that Oct is prime fishing time on NC Outer Banking institutions and 4wd is a necessity, can I manually put car or truck in 4 Hello by pulling the cable that goes into actuator? for A short lived deal with. Back again diff seems to lock but is difficult to inform around below, much too flat and much too dry.

Upon talking to a few yards, they evidently just take these modules out ($$$$$$$) and easily Lower the connector off and sell it Together with the module. So, that really only leaves me to a scrap garden that permits you to stroll around… and haven’t eradicated the module… don’t wanna go there.

Dan states: December 17, 2007 at eight:33 am I've a 99′ S10 Pickup and 4wd works good but the front drive shaft will not likely disengage within the axles when switched to 2wd. Fundamentally the transfer circumstance is switching from 4wd to 2wd nevertheless the front axle is often engaged. I traced the cable cable back towards the vacuum actuator beneath tha batery and located which the cable is just not certain up however the actuator alway has vaccuum to it No matter Should the car or truck is in 2wd or 4wd.
Appears like a front diff difficulty. I’m unsure on the many years, even so the tranny shop which i had mine in the beginning checked for this issue as it really is, evidently, typical.
I discovered a forum where a man experienced a challenge where his 99 Blazer wouldn't shift to 4HI. When he pushed the 2HI button, The sunshine flashed but absolutely nothing happened.
