I have discovered I could possibly get it out of 4HI in one of two techniques. If I park though stuck in 4HI and depart the car for some time, when began 4HI will flash and it reverts back to 2HI. OR If I set the truck in neutral, press 4LO (it goes into 4LO) then press 2HI, You can find clunk and it goes again into 2HI.
Josh claims: December 21, 2007 at 5:14 pm Im publishing this since not too long ago I've worked on two s10 blazers With all the exact issue and everyone kept telling me to examine vacuum and plus the acuator. First off each of these the 4wd light-weight would mild like it absolutely was Doing the job although the front axle was not partaking i checked the acuator and it had been Performing so i jacked the auto up and made an effort to manualy interact the axle without having luck. So i made a decision to pull the axle tube from the passenger side and Check out the locking hub.
1st, your tranny is not going to change into 4Lo at 60 MPH — it truly is intended to change ONLY in the event the transmission reaches speeds of 3MPH (5KM/H) or Significantly less. The flashing suggests that the TCCM is trying to shift from two/4Hi to 4Lo, nonetheless it cannot because of the pace now staying traveled (consequently why it went into 4Lo for your wife at the car clean) — it will eventually flash for thirty seconds (I feel it’s thirty seconds) then revert back again on the mode it had been last in (ie.
Unplugging the TCCM isn’t an excellent plan since it really doesn’t attain just about anything. If you are trapped in 4WD (which it looks like you are), unplugging the TCCM will likely not get you back again to 2WD. Nevertheless, I don’t desire to show you to continue to push the car with out figuring out even further facts — you'll have a dilemma With all the gears/forks inside the TC which may not enable the encoder motor to bodily swap modes — naturally, driving the motor vehicle With this issue would only lead to higher hurt.
Heck, if ya desire to “hack†it jointly, you could always remove the module in the aspect of your transfer circumstance, Slice a hole through the flooring and set an true shifter with the flooring and connect it to your pin to the transfer scenario (I wouldn’t advocate this on an ’03… maybe go away that trick for one which is falling apart and you don’t want to invest A further dime on it!) — You'll be able to shift into 4WD manually (All over again… NOT Suggested with a street vehicle!!).
Our whims and wants are irrelevant, compared to the turning wheel of the whole world. I'm who I'm. Belief no-one but your family and friends. The wheel turns in spite of us. Devices appear and go. All empires fade. Time is often a healer. The seasons never change. The Solar will not treatment what it rises over.
However, I'm able to’t give you a definitive solution to your trouble, but if I'd to mention, I’d look elsewhere, aside from your TCCM (encoder or transfer circumstance)… but then again, I’m not a mechanic both… so I am just guessing!
I didn’t understand I'd lost the inbound links towards the schematics in addition in the conversion. What I have, I have included back into the write-up at the best of your webpage. I hope this can help!
Although I don’t really have any working experience with the problem you describe, it appears like a swap / sensor to me. I do know There exists a pace sensor that stops you from putting the procedure into 4Lo while you're wheel alignment near me touring at a velocity of bigger than 5MPH (8KMH) — if that's the scenario, the 4Lo mild should flash until finally you decelerate to underneath 5MPH, then it need to fall into 4Lo.
What it can be is really a nut no larger sized than my thumb with three vacuum strains into 1 end and what is apparently a spring loaded ball on the opposing end. The one that I took off my blazer I can certainly push this ball out and in with the casing.

Rudy claims: March 24, 2008 at 3:38 pm I'm having a challenge with my 4WD not heading into 4HI, I push the button and practically nothing transpires. I set the truck in neutral and strike 4LO it goes in, then I press 2HI and it goes again. When I have it in neutral and press 4HI both equally 4HI and 4LO lights flash and after that goes again to 2HI. I read through that when you jumper pin 13 on the data url cable to ground, then convert important to the ON posture the lights to the 4WD buttons flash a code, so I tried it and absolutely sure ample a code of two flashed which means motor/encoder failure.
I found a forum where a man had a challenge exactly where his ninety nine Blazer wouldn't shift to 4HI. When he pushed the 2HI button, The sunshine flashed but absolutely nothing transpired.
