If this is something I can repair service myself that'd be terrific, but should you all Assume it's best to simply get it to a store I am able to try this far too, I just do not have Considerably cash to spare and the only real bik... Browse additional >>
I’ve tried out stopping and putting it in park in advance of switching and, although this did function a lot of the time, not each time. Also, over the time it takes to modify, the truck tugs a bit to the ideal. Identical to it had been slightly outside of alignment. Having said that, just after it switches, the tugging stops.
I discovered a forum where by a guy had an issue exactly where his 99 Blazer wouldn't shift to 4HI. When he pushed the 2HI button, the light flashed but absolutely nothing transpired.
That’s some very good information and facts to have. Remember to do let me understand how you make out With all the encoder motor alternative.
The, it is best to attempt to put it in 4WD and find out if any with the wires improve (they should drop their energy) — you'll have to do this numerous periods to browse the various wires — and an assistant are going to be very useful! In case you’re not obtaining the previously mentioned results, Check out a similar wires in the TCCM as see if the final results modify.
As to the encoder motor becoming fried as the TCCM “got corroded and shorted it out” — all over again, it doesn’t seem to be more likely to me. You will find (off-the-top rated of my head) 7 wires in between the TCCM and also the encoder motor. 2 of these are electricity (+/-) and so are FUSE shielded. four of them are sign strains and the final a single is signal ground. If the bottom wire was corroded and shorted (to what?
As with the vacuum change you linked to above — could quite effectively be the condition. For $18.ninety five, it’s low cost to see! Nonetheless, for pennies it is possible to take a look at it — NAPA (and possibly Many others, like PepBoys, and so on.) may have vacuum hose connectors — male to male connectors will help you to stick 2 vacuum lines alongside one another.
Verify your specs. Search in your vehicle's repair manual for specifics about the proper alignment configurations. You ought to discover numbers describing the vehicle's perfect toe, camber, And perhaps caster.
I probably saved hundreds if I might have gone to the dealer. I would have finished the function myself, but I don't have a lift and that small portion was a soreness to entry, or perhaps get it out for instance.

 Should your camber does have to be corrected, it should be performed before changing the toe.[seventeen] Camber can't typically be corrected at home with regular resources,[eighteen] and without a doubt, for many cars and trucks it cannot be altered in the least without bending or replacing significant parts. Unless of course you might have experience with automotive mend and professional instruments, don't try to adjust this on your own.
Unsure if related but Be aware which the cassete is 7 speed and has no Filth seal (like I observed on other cassettes).
Ryan says: April two, 2008 at nine:24 pm Thanks for your reaction Have A Peek At THIS Site to my write-up earlier, And that i experienced pep boys do a vacuum take a look at about the process and they reported each individual thing was gave the impression to be Okay, so I purchased that four wheel drive swith from napa and set up it,(it went into the entrance axle correct wherever the cable from the actuator attaches), however no luck. so i could see some type of sensor on top of the transfer case with 3 vacuum traces hooked up to it, so i changed i, and Yet again even now nothing at all, so I've a few more issues…their is an additional sensor within the tail pice from the transfer case, I used to be instructed it is the pace Regulate sensor, could that be the issue?
denes says: June 8, 2008 at 4:28 pm The encoder motors usually fail around the 2002+ autrotrac (4 4wb buttons) blazers and s10 p/u’s. A printed circuit board Make contact with “cooks out” Within the encoder motor confimation switches. Just so you understand, the A,B, and C switches notify the TCCM what typical change postion they’re in. the P switch is actually a singal to your TCCM when to halt the motor (ultimate park postion). I'm pretty confident A is 2wd, B is 4wd hi, and C is 4wd small. Should you’re slightly intelligent w/ electronics, You may as well deal with the TCCM challenges w/ new relays.
