If I’m not mistaken 1999 and again, the vacuum swap is on top of the transfer situation. 2000 and up it’s about the firewall. If it’s in addition to the TC, it looks like a nut with three hoses sprouting from it.
The encoder motor is the first thing that comes to intellect. Once more, I have not tried this, however, if it were me, I would try and disconnect the encoder motor and take a look at once again (this could not get the job done because the method may well detect the unplugged encoder and not try to engage 4WD — the sprint lights should flash if it’s seeking to interact 4WD). In case you don’t blow a fuse Using the encoder motor changed, you have found your difficulty — effectively, sort of. From there it could possibly be the motor alone, a physical obstruction from the motor (the shaft might be frozen (corrosion) towards the transfer case protecting against the motor from going) or wiring amongst the encoder motor and also the TCCM (a brief from provide to ground).
I am able to’t let you know which way is which, but mark it where it is when you start and go from there (A method might be 4Hi, the opposite 4Lo).
The TCCM is Functioning, the encoder motor is Functioning, the front, suitable axle is participating, along with your vacuum traces are working (there are much more, but they are the crucial ones). The trick here will likely be to see what is 4Hi dependent, and why it gained’t kick into 4Hi.
What it really is is usually a nut no larger than my thumb with three vacuum strains into one finish and what appears to be a spring loaded ball about the opposing end. The one that I took off my blazer I can certainly push this ball in and out on the casing.
Also required is string or fishing line and correct steel rulers and protected stands to connect the string at wheel hub top. The stands I used were a list of jackstands.
How to tell If your TCCM is undesirable? Well, that’s a little bit far too involved for me to detail listed here (in essence, it entails systematic testing of the various wires). If you can go through a schematic, then you’ll know what to carry out with it — all schematics that you choose to’ll require are in article one of the thread.
I in fact sat all the way down to do a little work on the site yesterday, coupled with updating my backup push — that’s when the problems commenced. In any case, in advance of I transform this put up into a rant… I possess the schematics sitting down suitable in front of me, able to be scanned as soon as I am able to get this equipment restored.
The key to keeping every thing lined up rather than going down the road sideways is usually to define or evaluate Full Report the thrust-line of the vehicle and align Each and every wheel to this thrust line. The desired thrust line is the middle line of the car. That is measured, not from the human body, which is not positioned correctly adequate with respect into the suspension pivots to generally be valuable.
Any Suggestions? No one else seems to have had a challenge similar to this from what I have go through. I value any feed-back.. Does it sound just like a vacuum trouble somehweres?
Hey $140 is fairly darn excellent when compared to a few of the estimates I've found folks get to repair their 4WD! Regards;
Bear in mind, grounds are Crucial that they're Superior. I'd appear somewhat harder at your motor electricity lines than anything at all — it would be These lines which the fuse could be blowing (I'd Consider — however you haven’t stated which fuse is blowing, as well as the 4WD process has two or three them — I feel I posted them in a very reply in this article somewhere!).
It doesn’t seem like it’s the exact same kind of technique, so I’m not really certain what to advocate to you personally. My process is actually a purely electronic a person (where you force a button, which activates a motor to vary modes in your case)… yours appears like a mechanical technique where you interact the 4WD manually (floor shifter) and The sunshine arrives on only as an indicator.
Hello Les — I didn’t recognize that Raymond had uploaded them to the file server — I assumed they were part of a site that saved that data (ie.
