Ryan claims: April two, 2008 at nine:24 pm Many thanks for your reaction to my submit previously, And that i had pep boys do a vacuum examination to the system plus they reported each and every point was appeared to be Okay, so I purchased that four wheel push swith from napa and mounted it,(it went in to the entrance axle appropriate exactly where the cable from your actuator attaches), however no luck. so i could see some form of sensor along with the transfer circumstance with three vacuum lines hooked up to it, so i replaced i, and Yet again even now almost nothing, so I've a couple much more concerns…their is another sensor on the tail pice of the transfer case, I had been told it's the velocity Manage sensor, could that be the situation?
Thanks for your Recommendations on uploading pictures. Are you able to please insert this to my unique write-up. I’d seriously like some assistance on this.
In case you consider the schematics, you are able to begin to see the motor is solely “controlled” because of the TCCM via sign wires. I suppose it’s achievable that if one of the motor wires ended up for being shorted it may lead to damage to the TCCM — do I think Here is the circumstance?
I probably saved hundreds if I would've absent into a dealer. I might have accomplished the do the job myself, but I would not have a raise and that tiny part was a soreness to entry, and even get it out for instance.
I'd a similar challenge on my 2000 sonoma. The dash lights around the 4WD switched did not mild up. I punched within the section amount on Google and found your site. You termed it appropriate – pins 1 and 6 wires corroded and broken. I couldnt have the terminals in time, so I cleaned out the connector, also cleaned the pins, stripped off some refreshing wire.
Of course, right after changing the TC or maybe the encoder, I'd reset the program by disconnecting the battery for one/two hour then cycle the ignition from on to off three times.
i place it in park, and yet again nothing at all. the one way to interact it (no buttons flashing in any way when in park or push) is to put it in neutral, and yet again only will go into 4low.
Hmmm, sounds like you have another system there — Hop Over To This Website appropriately, I are unable to assist you to any additional as I can only assist with what I am knowledgeable about.
Hmmm… doesn’t audio like a TCCM issue… sounds more like an encoder motor trouble, or possibly a transfer situation trouble.
If it doesn't shift, or only moves partially, you have both a leaking vacuum line, your vacuum change is shot (see pic inside a post previously mentioned) or your diaphram is leaking. Employing a pair of ViseGrips will help you to exam the front, proper hub, but I wouldn’t endorse leaving it like that — for one particular, the region under the battery is extremely modest — I couldn’t obtain the ViseGrips on and place the battery again in place (which I wouldn’t need to do in any case… just testing). Besides, the ViseGrips are likely to tear up that cable and now there is a cable to replace as well.

As I'm not a mechanic, everything which i understand about the Blazer 4WD process has, basically, been posted right here — you merely have to examine.
Track down your tie rod finishes. The tie rods tend to be the relationship involving your steering process and also your wheels. The rod ends are L-shaped sections often identified near The within on the wheel.
As I mentioned to a poster previously mentioned (two up from this a single), it sounds to me like it could be a button assembly, wire involving the button assembly and TCCM or even a TCCM dilemma.
