Jim states: February twenty five, 2008 at 4:07 am Probably you can assist me. Today I still left for get the job done and my truck was in 2HI. About five minutes down the road no lights were being on, in my four×four switch on the dash. I pushed the 2HI button and it lit proper up. My truck does go into 4LO as I am able to hear and truly feel it engaging. My truck also seems to go in and out of 4HI and 2HI.I found a ice spot around the pavement and when its in 2HI it will spin , but when I hit 4HI I hear a slight clunk and it'll consider off like its in 4HI.
Well, it’s starting to be much more aggravating acquiring those same thoughts again and again and in excess of… but now in random threads! Anyway, the opinions for this thread happen to be reopened so I can, all over again, reorganize the responses from other threads and put them back right here.
The new one particular I place in it beside not possible to press in. The end with the ball will get screwed into your transmission and it seems like the vacuum program controls the motion of that. (from my guess)
In the event the do, the challenge is in the wire somewhere among the TCCM along with the encoder motor — and I don’t envy you needing to come across it, if that's the situation. Utilizing what I have explained higher than, and a few standard logic, you should be ready to convey to while in the TCCM and encoder are speaking thoroughly.
Rudy suggests: March 24, 2008 at 3:38 pm I am obtaining a problem with my 4WD not heading into 4HI, I press the button and practically nothing happens. I put the truck in neutral and hit 4LO it goes in, then I press 2HI and it goes back. Once i have it in neutral and push 4HI each 4HI and 4LO lights flash and afterwards goes back to 2HI. I browse that in the event you jumper pin thirteen on the info link cable to ground, then turn vital towards the ON placement the lights about the 4WD buttons flash a code, so I attempted it and guaranteed plenty of a code of two flashed meaning motor/encoder failure.
If you select to begin a new Discussion board subject matter, you may connect data files to your put up. If you end up picking to add an image, it is going to develop a new subject matter within my site (which I will then shift being provided inside your first write-up).
OUCH! That hurts. Yeah, this is admittedly The main reason that I set this information and facts up to begin with. I'd a preposterous quotation initially, they usually (the dealership) hadn’t even looked at it — they had been just likely to get started on changing components.
If it does not shift, or only moves partly, you've both a leaking vacuum line, your vacuum switch is shot (see pic in a very write-up earlier mentioned) or your diaphram is leaking. Using a pair of ViseGrips will allow you to test the front, appropriate hub, but I wouldn’t recommend leaving it like that — for You Can Check HERE 1, the realm underneath the battery is incredibly compact — I couldn’t receive the ViseGrips on and set the battery back set up (which I wouldn’t want to do anyway… just screening). Besides, the ViseGrips are likely to tear up that cable and now you've got a cable to replace also.
I’ve tried using halting and Placing it in park before switching and, Whilst this did get the job done a number of the time, not each time. Also, in the course of the time it takes to switch, the truck tugs marginally to the appropriate. Similar to it was a little out of alignment. However, after it switches, the tugging stops.
Sorry, can’t enable you to with that a single — the Silverado I don’t know. It sounds like you may have AutoTrack though. As I mentioned to the earlier poster, I don’t know Considerably in any respect about AutoTrack, in addition to it’s a “set and fail to remember†sort program.
Something you can Examine rapidly is to lay down beside the auto and possess a person Slowly and gradually generate forward (while in 4WD)… you’re wanting to see In case the driveshaft through the TC on the front diff is in fact turning. Whether it is, the problem is ahead of that (ie. front diff), if not, the challenge is inside the TC.
Remember, grounds are VERY important that they are Fantastic. I'd glance a little bit more difficult at your motor ability traces than anything at all — It will be These strains the fuse would be blowing (I would Assume — but you haven’t said which fuse is blowing, along with the 4WD procedure has a few them — I believe I posted them inside of a reply in this article somewhere!).
Jodie Perry says: November thirty, 2014 at nine:21 pm Working on a 2000 Blazer and possessing exactly the same trouble as many are With all the 4 wheel travel not participating. I seemed on the web and discovered that the most common difficulty would be the transfer case vacuum switch. After numerous hours crawling beneath the Blazer and observing quite a few video clips over the location, I gave up and jumped back again on line to determine what I'd skipped. Evidently, I found out, that For those who have the 4 button four wheel travel selector, you don’t have a vacuum turn on the transfer situation…..you have the TCCM, an actuator along with a vacuum actuator switch. I checked out the actuator initially of the method and the cable was totally free and very clear. Went ahead and lubed it up for good measure also.
a number of people informed me that it absolutely was most deffinetely the encoder motor. so i tried to vary it and Once i did it set the transfer circumstance into nuetral as well as car goes nowhere and along with which the 4wd mistake ligth on my sprint will never go out.
