Blazer 4x4 tccm
Hi I have a 94' Chevy Blazer s10 4x4. I just replaced the tccm module and it went out on me in three weeks. I cant afford to get a new one for a while, and I want to go out on the lake Ice fishing with the 4x4. Is there any way to bypass it or manually turn it on. I herd somthing about running the vaccume line right to the transfer case? Any help would be great.thank you

Re: Blazer 4x4 tccm
The transfer case control module controls the transfer case shifting. It always has vacuum going to it. The transfer case controls the vacuum to lock in the front axle.
The only way to bypass it would be to take the encoder motor off the transfer case and manually turn the shifter shaft. |

Re: Blazer 4x4 tccm
Is the encoder motor the same thing as a TCCM? Where is it located in a 1994 auto 4.3 Vortec
