I'm perplexed , I have a 1994 S10 Blazer 4WD 4.3L V6, Vin W.
I have access to Alldata for this vehicle. I am trying to locate or identify the TCCM . It does not appear to be where Alldata says it is susppose to be. ( I don't know how to add a Image). Supposedly attached to the back of the ECM which is mounted somewhere on the passenger side (RH, right hand) on the back of the I/P (instrument panel). Can't find a picture of what it is suspposed to look like. I have spent hours going through information so I have learned a lot. I need to find the TCCM to check the connections and voltage values.
Help

 

It's behind the glove box on the passenger side. You will need to remove the bottom trim/kick panel to gain access. Once you have everything under the dash on the passenger side you will see it tucked up behind the glove box. It will be attached to the back of the ECM like you mentioned.

 

Thanks for the Help! It was located just as you said.Alldata missed it on that one. I put 2 pics referring to the TCCM location on my album for future reference.

Thanks again

 

No problem! Glad you found .

 

Is it located the sme place on an s10 pickup? Thank you..

 

hey just winding if any buddy has the wiring diagram for the tccm id like to check if there are supposed to be hot neg ?

 

This thread is ancient bro, but for parity sake, No, if you have 12v between ground and another ground you have a problem, the TCCM iirc will run reverse voltage to the motor for control, i think. Start a new thread and ping me there.

 

how ?

 

I need the pins position mine might be wrong ?
