I'd say a Silverado one would be more correct since it's also a 1500 not a wee little blazer

Does anyone offer a remanufactured tccm for a 96 Tahoe?

mounted far left of steering column but first why do you need to replace it?

dealer only likely.

Hello and thanks.
First of all I discovered there was no scan data on the Tech 2 for that year.
Jumpered pin 4 and 13. Sometimes it would read code 1, othertimes it would read codes 1 and 2, or just code 2. Seemed strange to me. Initilally all three button lights were flashing while I was driving around in 2wd (without me pushing any of the buttons). Now none of the lights are working except for the flash during power-up (then they all go out)
When I jumper the pins now, none of the lights come on. In other words, I can no longer extract codes. Either the tccm or I am confused. Never seen the symptoms change like that before yet I have never heard of a tccm failing. I believe the tccm is unique for that year.

code one indicates that you have a power supply issue with the #2 fuse 20 amp labelled tcase. it provides the hot at all times power and the code means it is getting interrupted some how. solve that first and the code 2 might clear out as well.

oh and that orange wire splits in three and enters the tccm in three different cavities just so you know.
