Ryan claims: April two, 2008 at nine:24 pm Thanks for that response to my put up before, and i experienced pep boys do a vacuum test to the procedure and they stated each and every point was seemed to be Alright, so I purchased that four wheel generate swith from napa and put in it,(it went into your front axle correct wherever the cable within the actuator attaches), nonetheless no luck. so i could see some type of sensor along with the transfer case with 3 vacuum traces attached to it, so i replaced i, and once again even now very little, so I've a couple extra thoughts…their is another sensor to the tail pice with the transfer situation, i was advised it is the velocity control sensor, could that be the challenge?
Extend a string. Having an assistant, take a bit of string or wire and stretch it amongst the lines about the entrance of the tires, In spite of the spindle, and measure the gap about the string.
For those who found any indications of corrosion, I'd personally strongly recommend unplugging the module and applying some “dielectric gel” to your plug then reconnecting it.
Raymond Dunne suggests: January seven, 2008 at 10:27 am Perfectly after alot of time on my 2001 Jimmy 4wd technique I am nevertheless stumped. Commenced that has a clicking sounds from front finish so I checked vacuum actuator and it’s doing it task given that I loosened up the cable. Truck is not going to go into 2hi or 4lo so I pulled the Regulate module and checked wiring. Big orange wire on electricity connector was protected in corrosion and just one wire on 32 pin connector was corroded.
I really don’t provide the encounter to state definitively Sure, or no — but I desire you the ideal of luck. Please, allow us to understand how you make out.
I could be Mistaken with this, but standard logics (plus the schematics) tells me to start checking out the wire that stops the TC from shifting if the A/T is in gear.
Besides camber and toe, there is a 3rd alignment evaluate called caster. Caster is definitely the angle of your steering axis when considered within the aspect of the vehicle. Caster is very difficult to evaluate without specialized resources and unattainable to regulate in your house.

I have Chevy 2001 Blazer. The situation I'd is that I'm able to’t activate the 4Hi. So I went to dealership. The repair service costed me $900 to interchange the TCCM.
I have discovered I could get it outside Visit THIS Site of 4HI in a single of two means. If I park whilst caught in 4HI and leave the car for a while, when started off 4HI will flash and it reverts again to 2HI. OR If I place the truck in neutral, push 4LO (it goes into 4LO) then press 2HI, there is clunk and it goes back again into 2HI.
As for the encoder motor currently being fried since the TCCM “obtained corroded and shorted it out” — yet again, it doesn’t look likely to me. You'll find (off-the-major of my head) 7 wires amongst the TCCM as well as encoder motor. 2 of them are energy (+/-) and they are FUSE shielded. 4 of these are sign traces and the last just one is sign floor. If the bottom wire was corroded and shorted (to what?
My to start with believed is TCCM complications. Disconnecting the battery is a standard procedure to reset any “OB (On-Board) computer” (although it’s ordinarily advisable to disconnect for 30 minutes — merely which means you don’t hurry it and it doesn’t reset). So, what you’re performing each time you are doing That is you are resetting the TCCM. From there, it really works, however , you in no way know for just how long.
These sleeves could be ruined by this process, so be mindful. You will find Distinctive instruments for rotating tie rods that may prevent hurt. Whichever method you may have, You should definitely Understand that the improve you might be building to the toe is going to be dispersed throughout two wheels. Every tie rod ought to be modified one/two of the overall ideal amount of transform in or out.
Regrettably, I’m not really the man to help you with the vacuum line as I’ve by no means experienced any problems with the vacuum and haven’t had the necessity to trace hoses. You may want to check this publish to discover if it'd be of any support to you personally.
