I have a 2000 Blazer that has started to shift it's transfer

Customer Question

I have a 2000 Blazer that has started to shift it's transfer case from 2 Hi to 4 Hi/Lo on it's own. I cleaned up some green connections at the TCCM and it seems better. It still pitches a fit irregularly. The shift motor always performs and I can get it back to 2 Hi. To keep it in 2 Hi at these times I have to hold the 2 Hi button in. Is this a sign of a failing TCCM?

most of the time yes this is a sign of a failing TCCM especially with green terminals at some of the terminals at the TCCM

if you cleaned them up and used some dielectric grease on the terminals and it still does this then the next step would be to replace the TCCM

if it was not shifting at all or was stuck in a shift so to say then usually the encoder motor is bad on the transfer case
