If it has been a very long time since you had an alignment, the threaded sections could be stubborn and demand some lubrication, for example WD40, to be able to make them switch.

Doug says: February 22, 2008 at 2:37 pm 1st, Kyle, wonderful page! found it attempting to uncover what's Mistaken with my Blazer. The 4 wheel drive will not interact…Was looking for the TCCM, you answered that problem, Going on to Amy, I discovered that my homeowners guide answered Amy’s issue, it claims that if you ultimately find yourself needing to use neutral to assist interact… the transmission indicator switch could have to have adjustment.
Sadly, I don’t know the solutions to most of the inquiries — I am able to guess, but that’s what it’s destined to be, a guess.
If you discover that it IS your problem — a diode along with a capacitor must resolve the situation. Everything you do is receive a diode (1N4148) and position it on the logic supply line on the TCCM (the polarity marker, a foul, in the direction of the TCCM), and area a capacitor (100uF 36v need to do it) in between the diode as well as the TCCM. What this does is helps prevent the battery from pulling energy FROM the TCCM (via the diode) plus the capacitor tends to make certain you've adequate energy there to “briefly” operate the TCCM whilst the car or truck battery is remaining drawn from.
What I’d do is go out and start testing the TCCM and connections (When you've got that ability). I go through a large amount of it On this submit.
Buffalo, eh? I listen to you — I’m just north of you in Ontario, Canada. You fellas been finding pelted this 7 days way too? We acquired eight inches yesterday, which started out all around 2:00pm — just in time to the travel house.
Another issue I observed was that you just explained the lights on the dash will flash whenever you press 4Hi — this informs you that the button for 4Hi is Performing, plus the TCCM is accepting the sign from it. So, it boils all the way down to a dilemma somewhere involving the TCCM as well as the encoder motor — I'd personally suspect the TCCM — quite possibly wiring, or potentially a foul TCCM.

As I'm not a mechanic, almost everything that I know about the Blazer 4WD procedure has, virtually, been posted below — you only really need to read through.
I’ve continue to got to receive some schematics posted for an additional visitor poster previously mentioned — hopefully I'll remember to Go To THIS Web-Site do so right now. Regards;
Sadly, it’s been Just about nine decades since I bought my Blazer and have no further more info to suit your needs other that what has Beforehand been posted here.
