Nicely, it’s getting additional annoying getting those same concerns again and again and more than… but now in random threads! In any case, the opinions for this thread are actually reopened so I can, again, reorganize the remarks from other threads and position them back again here.
The very first thing to check, even though, are your fuses. If there isn't any lights within the sprint, then you may not have “logic†electricity on the TCCM (logic energy is +5VDC). The logic power is provided in the courtesy lights (do your interior dome lights occur on after you open the door?
PS – I have modified the options to permit registered associates to upload pictures/files. If you want to upload, you should register. Sorry, but the spam and other crap is just absurd any more.
If you DO NOT listen to the “simply click-clickâ€, there is a negative relay inside the TCCM. The good news — you can obtain a alternative relay at your local electronics retail outlet and change it in the TCCM. You may need a soldering iron and many essential electronics expertise, but it is extremely effortlessly realized (two or three points to unsolder and then resolder the new relay in place).
But rather into the suspension pivots by themselves, and also the midpoint among them. I marked the thrust line by jacking the vehicle up and measuring among the suspension perches and after that scribing a center line involving the perches on something which needs to be visible in the event the vehicle is on It is really wheels. The marks I applied might be witnessed in the two photographs beneath. Click the pictures to check out a larger Model
As with the vacuum switch you linked to above — could very perfectly be the problem. For $eighteen.95, it’s cheap to discover! On the other hand, for pennies you are able to test it — NAPA (and doubtless Many others, like PepBoys, etc.) will have vacuum hose connectors — male to male connectors will help you to adhere 2 vacuum strains collectively.
I can not offer any further more recommend besides what I have now posted right here. I removed my Blazer in 2007.
First, your tranny will likely not shift into 4Lo at sixty MPH — it truly is intended to shift ONLY in the event the transmission reaches speeds of 3MPH (5KM/H) or Considerably less. The flashing implies the TCCM is attempting to change from 2/4Hi to 4Lo, nonetheless it cannot due to the velocity at this time becoming traveled (hence why it went into 4Lo for your spouse at the vehicle wash) — it will flash for thirty seconds (I feel it’s thirty seconds) after which you can revert back again into the manner it had been past in (ie.
Guest claims: December sixteen, 2008 at six:forty one pm perfectly i introduced my truck in and told them they could exchange the encoder motor, not sure what was precisely Improper with it, they reported it absolutely was enguaging only fifty percent way then kicking back out. nicely not sure what could result in this, i requested them to inspect all wires into the tccm and find out If your wiring may be the challenge, they usually said that whenever they mounted my tccm previous calendar year they must have also changed the encoder motor.
What I'm assuming is happing is, the pullup resistor pulls the line significant (give is electrical power, so it ought to examine +5VDC), the TCCM will pull a person, or maybe more (may be combos for numerous modes, I don’t truly know) from the signal strains minimal to indicate the manner to your encoder motor which, in turn, moves the transfer case accordingly. Yet again, I’m working on some presumptions in this article.
It’s not easy to say what your challenge is. I’d get started with investigating the encoder motor — if you can hear it run briefly, then what I might do is take it off the transfer situation and check out to have interaction 4WD then — look at the motor and find out what it does — check out it in all modes (2Hi, 4Hi, 4Lo) and enjoy the motor. If that is apparently Alright, another factor I might do should be to attempt to manually change the TC with the “tab†That ought to now be protruding url with the aspect of the TC (beneath the encoder motor that you removed) — it is this tab which the encoder motor turns to have interaction the different modes.
two) the vacuum change also communicates With all the TCCM — no vacuum as well as your lights will most likely flash continuously even though attempting to have interaction 4wd, but won’t have interaction until finally all 4wd parts, once again, talk to one another.
Another place for 4WD vacuum is beneath the battery — but that is kind of a distance within the motorists doorway, Even though anything can be done.
Seems to me like the transfer circumstance gears / forks — in the event you dig again by many of the posts, I have explained the trouble you request of.
