My two wheel push would interact but not my 4. I read about the tccm plus the vaccum switch and to my sure amazement the vaccum line experienced damaged off the switch. I fixed this situation and now my four wheel travel is Performing yet again. The info you posted saved me a trip to some vendor!!!
Hmmm… how ’bout sizzling glue? I basically plugged in the principle connector to your module (immediately after sealing all of it up with dielectric gel… which might have prevented this to start with) after which inserted the wire into pin #one and manufactured the relationship, and precisely the same for pin #6.
Josh claims: December 21, 2007 at five:fourteen pm Im publishing this simply because just lately I've labored on two s10 blazers Along with the same trouble and everybody held telling me to examine vacuum and plus the acuator. To start with off both of these the 4wd gentle would gentle like it was Doing work but the front axle wasn't engaging i checked the acuator and it was Doing work so i jacked the vehicle up and attempted to manualy have interaction the axle without luck. So i decided to pull the axle tube off the passenger side and Verify the locking hub.
The TCCM is working, the encoder motor is working, the front, ideal axle is partaking, and your vacuum lines are Doing the job (there are actually more, but these are generally the essential ones). The trick right here will probably be to find out what on earth is 4Hi dependent, and why it received’t kick into 4Hi.
Here are some much more photos of your TCCM. They're not mine, but I honestly can’t try to remember who sent them to me presently (I just found them although cleansing up the backend of the site and didn’t know they had been there.). When they are yours, allow me to know And that i’ll write-up Picture credits. Thanks!
It’s challenging to say what your trouble is. I’d get started with checking out the encoder motor — if you can hear it operate briefly, then what I'd do is just take it from the transfer case and check out to engage 4WD then — observe the motor and see what it does — test it in all modes (2Hi, 4Hi, 4Lo) and observe the motor. If that is apparently Okay, the following thing I might do is to try to manually shift the TC Along with the “tab” that should now be sticking out in the aspect of your TC (beneath the encoder motor that you simply eliminated) — it Is that this tab the encoder motor turns to interact the several modes.
Could minimal fluid bring about a challenge? Certainly. You don’t have to replace your fluid if it’s minimal — just major it up to the appropriate quantity. However, I’d be inquiring myself WHY it’s lower.
Mine would go into 4WD, the two Lo and Hi, but would from time to time slip away from 4WD (typically in Hello) resulting in a loud grinding/banging noise. When screening it in 4Lo, it might often not go anyplace, then Impulsively drop into equipment like and snap your head back (using a hell of the bang too).
I submit what I've encountered in the course of MY OWN REPAIRS — I publish this information and point out that, but somehow individuals never study the posts, but they depart responses or comments inquiring me how to fix something that I am aware nothing about.
Or, as A final vacation resort, please Be at liberty to Call me by means of the Make contact with type, leave your email deal Going Here with stating you’d wish to send out me some pics and I'll respond with an address you may ship them to.
Regretably, your thoughts are very vague and audio similar to every single other dilemma, as described earlier mentioned.
Looking at your to start with views on it, And that i’d really need to say I agree along with you. Does the 4Hi light-weight occur on any time you to start with change The main element for the ON place with no aiming to start out the auto?
Except you've got encounter performing suspension work, you will probably really need to choose your vehicle to a specialist mechanic.
