My 2 wheel travel would interact but not my four. I examine the tccm and also the vaccum swap and also to my sure amazement the vaccum line had damaged off the swap. I set this issue and now my four wheel travel is Doing work yet again. The info you posted saved me a visit to the seller!!!
I read all of the critiques about American vehicles and like a idiot I purchased this Blazer because it seemed like a superb deal. I’m even now seeking to figure out many of the electrical troubles out. Our great auto businesses considered they had been going to provide junk endlessly and we were going to continue to keep buying it. Incorrect!!!! This is often my final American automobile until a little something improvements. Just this 7 days I junked my Pontiac Along with the famous Quad4 motor that broke a connecting rod twice.. A few many years in the past I scrapped my Dodge Caravan once the trans mission EXPLODED 2 times. And that i do mean explode! NO A lot more GM, Ford, Chrysler!!!
Scott states: January 2, 2009 at 8:03 pm ok no corrosion no wetness whatsoever also Once i question it to change i still in this article it click in the tccm. Also a new factor I forgot it should be in nuetral to change into or from four low when its in nuetral i also can here the little electrical motor over the transfer situation my future imagined is to remove the motor with the transfer case to determine if I am able to shift it maunlly but that will involve alot of dissmanlting there’s many points in the way Is that this vital.
Raymond Dunne suggests: January 7, 2008 at 10:27 am Effectively soon after alot of your time on my 2001 Jimmy 4wd method I am nonetheless stumped. Started off that has a clicking noise from front finish so I checked vacuum actuator and it’s accomplishing it position given that I loosened up the cable. Truck will never go into 2hi or 4lo so I pulled the Management module and checked wiring. Significant orange wire on electrical power connector was protected in corrosion and just one wire on 32 pin connector was corroded.
My four lo will work. And that i listen to the module click when it moves into 4lo. but when i test to maneuver into 4 hi the lights flash then goes straight to 2hi. I had been questioning if you can plaese aid?
Regrettably, I have not encountered what you are describing and may only supply suggest for things which I, Individually, have done as I am not a mechanic. I have no idea what this pin is, or how significantly it need to shift.
2 Speedy visual inspections could fix your issues with the 4 wheel push not Performing, flashing lights, wont go into 4whl low. I acquired alot looking through this site and needed to ad the onfo I gained and the final results I acquired in about 30min.
Bob B claims: April thirty, 2008 at 11:33 pm Hello Kyle……..there is a good site and have study pretty much every item both you and your viewers have problems with but my wifes truck has the Grand Daddy of issues and when you convey to her to market it she's going to realize. Listed here goes….I used to be permitted to drive her throughout the other day Once i heard what I believed was the blinker going and experimented with frequently to terminate the non blinking lites without achievements. Just after a few minutes the service four whl generate lite came on, once we parked I requested if this experienced transpired just before and she claimed Sure all the time but it surely goes away when I park.
When you listen to the clicking from the TCCM, that lets you know that the relays are Functioning and try to put the encoder motor in gear. There are many factors for this to happen, damaged/leaking vacuum traces to begin. The encoder motor wires may be bad. There's a “plastic bushing” that keeps a “fork” while in the transfer situation within the posture (nicely, the Visit THIS Site fork retains the gears in the appropriate placement)… If your plastic bushing is worn, it might cause the transfer situation to not change (this happened to me, however the indicators were being the method would change to 4Hi/4Lo, which has a large clunk, and it absolutely was quite challenging to obtain it back again out of 4WD.)
I introduced my truck into a tire/alignment shop very last 7 days to have the new wheels and tires mounted, balanced, aligned.
Roll the vehicle. Press the vehicle forward a minimum of ten feet While using the steering wheel unlocked to ensure the wheels are straight.

Current 12/12/07 – I just wanted to include to this publish which the TCCM has two relays within just that Manage the actual switching in the encoder motor — you that is certainly That which you hear “clicking” after you test to engage the 4WD procedure.
This is your camber.[thirteen] Repeat with the other front wheel. The 2 wheels should be concerning the similar and throughout the variety specified by your guide. Otherwise, your camber may need alignment. Repeat the process within the back.
