) — Check out that fuse! (Fuse #eight, I feel — it’s NOT detailed as obtaining nearly anything to perform Together with the 4WD program — I found that through the schematics.) You will discover a few fuses that I am aware of getting to accomplish Along with the 4WD method — on beneath the hood (20A), a single during the dash fuse paned (10A) and one other would be the courtesy lights (15A, I believe).

one) let’s start off with the straightforward points — Have you ever checked your fuses? Don’t assume that Because the fuses are labeled 4WD that they are the only ones in your 4WD program! Fuse ten (on my 2003 Blazer) is for that courtesy lights — but guess what? It also controls the logic aspect on the TCCM (+5VDC). Pin 6 (thinner orange wire) should deliver +5VDC and may be HOT Continually (meaning you need to be capable of read +5VDC on the line at any time, key on or off). The 2 significant orange wires are your +12VDC strains and they are controlled with the 10A fuse situated in place #15.

Examine the schematic “front axel change & pcm.jpg” — and afterwards have A different think about the wires around the TCCM (Transfer Situation Command Module), Found underneath the passengers kick panel.

I found a Discussion board where a man had a problem where his ninety nine Blazer would not change to 4HI. When he pushed the 2HI button, The sunshine flashed but nothing at all happened.

If it absolutely was the actuator, I’d Consider the front conclusion would pull to your remaining… the actuator controls the best front axle only (AFAIK). The remaining is always engaged Along with the front diff.

Dan says: December 17, 2007 at eight:33 am I've a ninety nine′ S10 Pickup and 4wd operates high-quality but the front travel shaft will likely not disengage from your axles when switched to 2wd. In essence the transfer scenario is switching from 4wd to 2wd but the front axle is always engaged. I traced the cable cable back again to the vacuum actuator less than tha batery and located the cable isn't sure up although the actuator alway has vaccuum to it Irrespective In case the car or truck is in 2wd or 4wd.

The only thing I am able to counsel, which may be of no price for you, is always to try and swap out the TCCM. You could possibly try a made use of a person in the scrap yard, however, you never ever definitely know what you’re having there (you might be in even worse condition). You will discover organizations that rebuild them (the last 1 I heard my buddy with the garage acquire was like $150, his cost, for the rebuilt unit), or, hopefully, your mechanic could have a good one particular around that you can use to see if that is the situation (obviously, Using the latter strategy, you need to have an excellent romance with your mechanic!

Besides, the ViseGrips are likely to tear up that cable and now you do have a cable to replace too.

It’s tough to say what your trouble is. I’d start with looking at the encoder motor — if you can listen to it operate briefly, then what I would do is acquire it off the transfer situation and check out to engage 4WD then — look at the motor and find out what it does — attempt it in all modes (2Hi, 4Hi, 4Lo) and check out the motor. If that seems to be Okay, the subsequent point I might do is always to attempt to manually shift the TC With all the “tab” that should now be protruding of the facet with the TC (under the encoder motor that you eradicated) — it Is that this tab that the encoder motor turns to have interaction the different modes.

I have found I could get it outside of Browse Around HERE 4HI in one of two strategies. If I park though stuck in 4HI and depart the vehicle for quite a while, when started 4HI will flash and it reverts again to 2HI. OR If I set the truck in neutral, press 4LO (it goes into 4LO) then press 2HI, There's clunk and it goes again into 2HI.
