Hmmm… it’s difficult to say — it could be as simple as the encoder motor sign strains staying corroded/ruined (Look at the schematics in the primary submit), or it may be the transfer case itself. If your lights get the job done as they ought to, then this tells me the 4WD system is engaging, executing what it ought to. I suspect the transfer case just isn't shifting thoroughly. As I explained to your poster higher than, it might be time to have your transfer circumstance checked by a tranny store.
positive adequate the vacume line was bad by the valve include. I initial altered the vacume turn on the transfer circumstance but it absolutely was only $sixteen And that i by no means have to bother with it once again. So for $26, and the wide info on this website, I expended about two several hours to receive it working. Can’t thank you enough.
The encoder motor is also terrible. Anyway, if worse comes to worst, you can unscrew the encoder module and manually change the transfer circumstance into any manner you want. Sadly, I can’t tell you which way is which — you’ll must figure that out with demo and mistake! Don’t fear, you are able to’t damage nearly anything — you’ll either be in two wheel travel, or one of many 4 wheel ranges. If it’s not 2 wheel, try out yet again until finally it truly is! (There will be metal “tab”, for deficiency of better text to explain it, sticking out of your transfer case — put a wrench on it and it should really shift with nominal effort. Under no circumstances FORCE Just about anything! Take it to get a travel and see That which you’re in. With any luck ,, you’ll get it on the main test!
Draw a line. Using the car even now up on the jack, keep a pocketknife, thin bit of chalk, or white pencil towards the center of tire tread. Hold your hand quite nevertheless and possess an assistant transform the tire one full switch, making a line throughout the circumference.
Consider the schematic “front axel switch & pcm.jpg” — and afterwards have A further look at the wires about the TCCM (Transfer Circumstance Regulate Module), Situated underneath the passengers kick panel.
Naturally, I'm able to’t promise This is certainly your issue, Specifically over the internet, and I hope it isn’t — but I would have it checked out professionally.
one) you are able to pull about the cable to have interaction the travellers facet hub — but it will eventually disengage if you release it as vacuum normally retains the diaphram closed, which holds the cable, which retains the hub engaged.
I didn’t Imagine just about anything of it besides that my Try THESE Guys Out ground heat was most likely about to blow in my facial area. The correct which i executed within the car parking zone in the nearby auto sections store took 5 minutes as well as vacuum coupler tube only cost about seventy five cents. Thanks yet again for saving me a butt load of money!
The 1st issue you'll be able to test your self. Get the schematics from the first submit and check pins 26 by 29 for logic power (+5VDC), employing pin 16 as your floor. You may additionally choose to get underneath the motor vehicle and examination the identical wires in the encoder motor. Examination the bottom wire there in addition.
$ten to fix your 4WD — great! Thanks for sharing that facts with myself and my visitors — I’m sure it will help a few people conserve lots of $$$!
Hey Shawn, When you Enroll in an account in this article, you ought to be in a position to add illustrations or photos listed here (I haven’t had any individual test it but, but I set it up just after Yet another guest claimed she could not upload images).

What it feels like, to me, is usually a wiring dilemma — probably involving the encoder along with the TCCM (underneath the kick panel). Have you pulled the kick panel and experienced a consider the TCCM wiring (as pictured int he 1st submit of the web site entry)?
