Ran the wire from the pin to a ground and the code read a 3, or flashed in 3's. Does that mean the module is out. When I bought blazer from the guy he had removed the motor because it was stuck in 4 wheel driver.

 

Anyone got any thoughts on this? I think the module is out but am not for sure.

 

I'm guessing you have the NV233 - 3-button system.

OBD2 NV233 Diagnostics

 

I bought my o2 with the 4x4 not working. Guy said it was stuck in 4 wheel drive and he took off TC motor so he could switch it into 2 wheel. He thought it had a bent fork in trans case. I put on a New motor, it's still not working. I ran the wire from the 13 pin to a ground and it flashed 3. I think my module is out am I correct?

Please DO NOT double post! Since you already have a thread on this subject, please keep things there.

Test all of the wiring and the switch. The diagrams are listed in one of the NV233 threads found in the Tech Article (DIY) Index. If all of that checks out, then you could possibly have a bad TCCM.
