PS – the “encoder motor” is the aspect that “holds” your TC in the various modes (properly, that’s not a hundred% accurate possibly — the encoder motor shifts from a single method to another — parts inside the TC actually “keep” you in that mode — in my circumstance, it had been a list of “forks” with plastic bushings that wore out — which does not audio like your problem).

The first thing to examine, though, are your fuses. If there aren't any lights within the sprint, then you may not have “logic” power for the TCCM (logic electricity is +5VDC). The logic energy is supplied in the courtesy lights (do your inside dome lights come on once you open the doorway?

You furthermore mght want to check the wires within the encoder motor as They may be exposed to the elements and *could* be destroyed by some thing flying up underneath your auto (not likely, but doable).

I really don’t contain the expertise to say definitively Indeed, or no — but I would like you the best of luck. You should, let's know the way you make out.

As I have stated many times throughout the 3 web pages of the put up… every thing which i find out about the Chevy 4WD system has been posted in this article. I don't have any additional details to provide. I'm not a mechanic.

). I have a definite “vacuum” sound coming from underneath the dash, near the heater core. At reduced speeds it “whistles” (like a leaking vacuum would sound like), and goes away at larger speeds.

What it sounds like, to me, is actually a wiring issue — most certainly concerning the encoder and also the TCCM (beneath the kick panel). Have you pulled the kick panel and had a consider the TCCM wiring (as pictured int he initial put up of this website entry)?

There is a schematic (on page one) with the front axle switch — it appears for being tied to floor through a “pull-down” resistor. When engaged, it should be pulled higher (+5VDC or +12VDC, I don’t know what it’s applying to the switch).

Keep your eyes on eBay — I just saw 1 go for $one hundred thirty five that a guy acquired new 6 months back which is scrapping the truck. You will discover them at the Chevy supplier, but They are really correct around the $500 mark — ouch!

I put up what I've encountered in the course of My very own REPAIRS — I post this information and facts and condition that, but by some means men and women never read the posts, nonetheless they leave suggestions or remarks inquiring me how to fix something that I do know nothing about.

so now i have a fresh transfer circumstance and as well as a brand new encoder motor which i cant placed on since Continue Reading it will not appear out of nuetral about the trasfer scenario Until i change it manually. and since I've to depart the encoder from the front axle wont interact for the reason that its not getting the rigth message.

Generally, the front motorists axle may be the axle that may be permanently engaged throughout the front differential (that doesn’t mean it’s usually driving… only in the event the front diff is engaged will it basically generate). The front passenger aspect axle engages when put in 4WD, via an actuator under the battery.

It’s hard to say what your issue is. I’d begin with considering the encoder motor — if you can listen to it operate briefly, then what I'd do is get it from the transfer case and try to have interaction 4WD then — enjoy the motor and find out what it does — test it in all modes (2Hi, 4Hi, 4Lo) and watch the motor. If that is apparently Okay, the next detail I'd do should be to try and manually shift the TC with the “tab” That ought to now be protruding of your facet of your TC (under the encoder motor that you just removed) — it Is that this tab the encoder motor turns to engage the various modes.

I taken out the battery tray uncovered the diaphram and it truly is working. could my challenge be vacuum? I assume I didn’t look challenging adequate simply because I didn’t begin to see the vacuum change by distributor and it’s fairly tight in there . Any tips? Thanks,Tim
