bewildered suggests: January 4, 2009 at 2:fifty two am I've a 4WD 2000 BLazer that gained’t disengage from 4HI. After i push 2HI I'm able to listen to the TCCM clicking as well as lights flash on 2HI but goes back into 4HI. I also attempted 4LO Which does a similar thing. Having said that, it does go into Automobile 4WD without dilemma. I’ve had the switch on the dash changed (the letters to the old a person wouldn’t mild up).
The encoder motor may be poor. Anyway, if worse relates to worst, you are able to unscrew the encoder module and manually change the transfer scenario into any method you want. However, I am able to’t let you know which way is which — you’ll need to figure that out with demo and error! Don’t be concerned, you could’t damage anything — you’ll both be in 2 wheel drive, or one of several four wheel ranges. If it’s not 2 wheel, try out once again until eventually it's! (There will be metal “tabâ€, for lack of better terms to explain it, sticking out with the transfer circumstance — place a wrench on it and it should transfer with nominal effort. Under no circumstances FORCE Nearly anything! Take it for any push and find out what you’re in. Ideally, you’ll get it on the very first try!
The turn on the dash doesn’t flash ,it lights up like it’s speculated to do like every thing is Doing the job thoroughly. The one thing i couldn’t come across was the vaccuum switch on the firewall. Any strategies?P.S. great Discussion board!

May very well be a TCCM dilemma, encoder motor challenge or simply a transfer situation dilemma — all of which has been covered within this thread.
Heck, if ya choose to “hack†it alongside one another, you can often remove the module with the aspect in the transfer case, Reduce a hole from the flooring and place an precise shifter throughout the floor and fasten it towards the pin about the transfer scenario (I wouldn’t suggest this on an ’03… maybe leave that trick for one that is slipping apart and you simply don’t want to invest A different dime on it!) — Then you can certainly change into 4WD manually (Yet again… NOT Suggested on the Road auto!!).
I used to be rather delighted once they held, that’s for sure! I mounted the module back around the body, reinstalled the kick panel and my 4×4 was back again in organization.
If I put the truck in neutral and push the 4lo it lights up as whether it is Doing the job. Neither a person appears to function as I received trapped in my driveway. You should assist.
I’ve meant to consider the heating program considering that like last Winter season — just by no means seem to get around to it (probably ’cause I don’t utilize it in the summer… WHEN I really feel like correcting it!
What it can be is often a nut no greater than my thumb with 3 vacuum strains into one close and what appears to be a spring loaded ball to the opposing close. The one that I took off my blazer I can easily press this ball in and out wheel alignment near 7704 of your casing.
In the event you consider the schematics, you can begin to see the motor is solely “managed†via the TCCM by way of signal wires. I suppose it’s possible that if one of the motor wires ended up to become shorted it could lead to harm to the TCCM — do I feel This can be the scenario?
I assumed I’d give it a attempt to see what I could do (the plastic bag you see from the 3rd graphic incorporates a few more spare connectors in case it at any time happens yet again… I’ll know proper where These are!).
The vacuum for the 4WD program begins about the drivers aspect, goes on the vacuum actuator in the course of the firewall (but down below the distributor and tough to see — This is certainly what I believe you hear — You will find a photo up about 10 posts or so) then goes for the diaphram beneath the battery.
Generally, this will likely emulate the button remaining pressed and may trigger the TCCM to have interaction 4Hi. If it does not, the problem is with the TCCM, most-probable. Yet again, Test pin five with the TCCM. You may also want to check out making use of electricity to pin five immediately within the TCCM and see if it engages 4Hi.
