Sherry claims: September 22, 2008 at three:15 pm I actually want I discovered your website just before I replaced my tccm. I are in copyright and my 4wd stopped working. I've a 2003 blazer and where I Dwell 4wd is surely an complete will have to. I took it to your shop and they might not find out the problem, so then I took it for the dreaded vendor. They gave me a estimate of $1800.00 to interchange my encoder motor and transfer case Manage module. I absolutely couldn't pay for this so I took the estimate and located the components on ebay, then I took it to the initial store and paid out them $200 to set up everything.
It’s not easy to say what your dilemma is. I’d start with looking at the encoder motor — If you're able to listen to it run briefly, then what I would do is take it from the transfer circumstance and try to have interaction 4WD then — look at the motor and see what it does — try out it in all modes (2Hi, 4Hi, 4Lo) and observe the motor. If that appears to be Alright, the following issue I might do is to try and manually change the TC Using the “tab†That ought to now be protruding in the aspect on the TC (beneath the encoder motor you removed) — it Is that this tab the encoder motor turns to interact the various modes.
Incredibly Skilled workforce. Lizzette & her feminine cohort just awesome! The estimators & complete male staff total professionalism! The tip results perfection!!! What incident? No-one wants to have an accident; but if you are doing please check Euro Collision South Loop. No have to have to buy anywhere else. I'm grateful to them...my motor vehicle was All set in file time!!!
I might Test your Huge orange wires as that you are receiving +5VDC logic as the lights are coming on about the dash. The +12VDC is useful for the encoder motor — Verify to you should definitely have +12VDC at both of those the big orange wires (They may be proper beside each other… and There are 2 substantial black wires beside them which have been floor). Notes: All black wires are ground — all orange wires are electrical power (hot). There is a 10A fuse (#fifteen) for your 4WD method, situated in the fuse panel. There is a 20A fuse, Found beneath the hood, that is certainly also with the 4WD method (I’ll need to look up the fuse amount). The 4WD technique also pulls from your 10A courtesy lamp fuse (#10).
No problem in the slightest degree… which was my sole intention… that will help Many others with the same problem (and help save a ton of money as well!).

Rudy says: March 24, 2008 at 3:38 pm I'm having a difficulty with my 4WD not heading into 4HI, I press the button and nothing at all comes about. I put the truck in neutral and strike 4LO it goes in, then I push 2HI and it goes back again. After i have it in neutral and push 4HI each 4HI and 4LO lights flash and after that goes back again to 2HI. I browse that should you jumper pin 13 Pop Over To This Website on the info link cable to ground, then transform critical on the ON position the lights around the 4WD buttons flash a code, so I tried it and certain plenty of a code of two flashed meaning motor/encoder failure.
Coming to Euro Collision and working with Gabriela was a wonderful practical experience. They may be extremely Specialist and sort plus the car was accomplished right before they approximated. Additionally, it appeared better still than it did when it was strike. Thanks!
Now, You will find a sensor over the front, proper hub to detect when it's engaged — I have not tried this, so I don’t know one hundred% of course, but If your front, appropriate hub just isn't participating, the technique really should detect this instead of enter 4WD.
I do know I’ve in all probability just rambled on and explained to you nothing — properly, that was basically my considered method when attempting to uncover a dilemma. I'm able to only hope it assisted. Let me know how you make out. If I visualize the rest, I'll update this publish.
We now have 4WD. My wife is impressed with me and my hat is off to you sir. You saved us large time. Will gladly fund your retirement account for what you may have saved us. Let me understand how.
I have a heater situation that I feel is tied on the vacuum procedure. Once the truck is warmed up, under 40mph, the heater blows amazing air, then at highway speeds it’s hotter than blazes! any feelings?
I have a 2003 chevy blazer and have no drive on the front axle. Once i thrust the buttons the tccm clicks, the buttons gentle and continue to be lit you can right here the motor on transfer circumstance operate (for a quick time) and no energy to front axle.
Hmmm… might be a couple of issues. First, if you can find into 4Lo, issues in all probability aren’t as lousy as they seem — this, basically, informs you that the parts during the process are Doing work.
