The next Inspection is within the motor bay significant up on the middle of the firewall. Inspect for vacuum on the swap after which you can make certain the hose is’nt weakened resulting in leaking (Mine was broken off) Extra warmth through the engine compartment will problems vacuum hoses and extreme curves or bending will cause problems with hose decay and failure.
Stretch a string. Using an assistant, take a piece of string or wire and stretch it among the traces within the front on the tires, even with the spindle, and measure the gap about the string.
I am drastically indebted to you personally. My new spouse’s 2000 Blazer dropped her 4wd a calendar year back. SHe found your Web-site with regards to the TCCM module corrosion, printed off the information and her mechanic set it. He was also impressed.
The very first thing I'd personally Look at is the 4Hi gentle — (maintain it uncomplicated) — does the 4Hi light-weight at any time arrive on?
Imagined I'd Supply you with an update on my 4wd scenario. As I indicated in my first put up, I had a vaccum line free. I thought it went to the canister inside the fender, what’s much more, I assumed it had something to do with my 4wd not Functioning. Nicely, that was the case. I found the attachment for that line within the canister. I acquired a fresh vaccum line (the just one I'd was weathered), set up it and hooked it up towards the canister. Then I went to your muddy spot within a sub-division next to mine, drove in the mud in 2wd. I just sat the spinning the rear wheels. Then I pushed the 4HI button, the light flashed to get a second, then arrived on reliable.
Yes, following replacing the TC or the encoder, I would reset the process by disconnecting the battery for one/2 hour and afterwards cycle the ignition from on to off 3 times.
The only real other point which i can suggest is really a “household mend”. Obviously, I do not know what type of difficulty you might be getting, but Allow’s presume you have dash lights and The sunshine DOES Visit the four×four higher (or lower) place — at this stage, listen to see whether you hear a definitive “click on-click” coming within the TCCM.
However it reveals in “4 wheel very low” I experience my upcoming move is eliminating the entrance travel shaft , and pulling the servo shift motor about the transmission , it appears to be like as If your are around nine wires intending to Try THESE Guys Out that servo motor, I’m I on the ideal tranck ?
If everything is engaging / disengaging effectively, I'm able to’t see it staying an issue as A brief correct. Of course, I wouldn’t advocate it for a permanent deal with (gotta say it!).
Or, as A final vacation resort, make sure you Be at liberty to Get hold of me through the contact type, leave your e mail tackle stating you’d wish to mail me some pics and I'll answer using an handle it is possible to ship them to.
Now, if you are doing listen to the “click-click”, then your TCCM is Operating and seeking to shift into 4WD — the problem, IMO, would then be With all the module that is actually over the transfer scenario (I neglect the expression for it at this moment) — it is an easy “motor” set up that basically moves the transfer scenario gears to the right manner.
Chris states: February twelve, 2008 at 10:forty eight pm Thanks to the reply Kyle. A result of the time along with the temperature outside in sunny Buffalo NY, I gained’t be trying nearly anything tonight. I'm looking to do all the things at Focus on lunch wherever its warm. To apparent up a couple of issues, I've checked the TCCM. I pulled the duvet off and checked the insides and all appears to be like excellent. Rusty within the out but no indicator of corrosion In the TCCM or perhaps the plug. I have visually inspected the EM connector various occasions. I have tugged over the wires, and it appears for being in good form, no corrosion or apparant broken wires. For the reason that previous post, I have exchanged the new EM with A further new a single which 1 is exhibiting exact same challenge so I am 99.ninety nine% certain it isn’t the motor. The outdated EM worked when I tapped it Using the mallet, but only for a brief time, in essence prolonged plenty of to get me in 2-hi. Both of those new EMs have not labored. What is absolutely bothering me is The reality that the new EM is installed and no blown fuse. Yesterday when I to start with place it in, the fuse blew in just a minute of starting off my truck.
Kyle, you could submit as you prefer.To include information, my seller was talking about changing the two computer modules linked to the 4wd, They said exact as after they changed them in ’05 that equally would have to get replaced at $1060 moreover tax and which was a mininum.
Jodie Perry says: November 30, 2014 at nine:21 pm Focusing on a 2000 Blazer and owning the identical difficulty as many are While using the four wheel push not partaking. I appeared on the web and discovered that the most common trouble may be the transfer case vacuum switch. After lots of hours crawling beneath the Blazer and watching a lot of videos on The situation, I gave up and jumped back again on the internet to see what I had skipped. Evidently, I learned, that When you've got the four button four wheel travel selector, you don’t Possess a vacuum activate the transfer circumstance…..you may have the TCCM, an actuator as well as a vacuum actuator swap. I checked out the actuator to start with of the process as well as cable was totally free and obvious. Went in advance and lubed it up permanently evaluate also.
