The 1st issue you'll be able to examination you. Grab the schematics from the 1st publish and check pins 26 as a result of 29 for logic electricity (+5VDC), utilizing pin 16 as your floor. You might also want to get under the car or truck and exam exactly the same wires with the encoder motor. Take a look at the ground wire there too.
Soon after cleansing up the corrosion on all remaining wires, and cleaning out the principle connector, I stripped and attached new clips to The 2 damaged wires and caught them in the key connector.

one) Allow’s start out with the easy items — have you checked your fuses? Don’t think that Simply because the fuses are labeled 4WD that they are the only kinds for your 4WD program! Fuse ten (on my 2003 Blazer) is for the courtesy lights — but guess what? In addition it controls the logic aspect of the TCCM (+5VDC).

The 2 large orange wires are your +12VDC traces and so are controlled in the 10A fuse located in location #15.
I am tremendously indebted to you. My new wife’s 2000 Blazer lost her 4wd a yr ago. SHe identified your Site about the TCCM module corrosion, printed off the information and her mechanic set it. He was also impressed.
