What it looks like is you may have an encoder motor trouble — This can be the motor to the side of your Transfer Case that controls the shifting of the varied “modes” (2Hi, 4Hi & 4Lo).
As for The interior workings with the transfer case, I go away that to the pros so I can’t remedy that dilemma either.
Very well, let’s begin with the most obvious trouble — the “leaking air” sound. Almost certainly this is a vacuum line that has possibly come off, or is damaged. There are actually a number of locations This might transpire — even so, hearing it with the motorists doorway open up might be an indicator that it’s coming both within the mainfold, or the 4WD vacuum switch (pictured earlier mentioned, located on the firewall).

I have a 2003 chevy blazer and possess no push for the entrance axle. When I push the buttons the tccm clicks, the buttons light and keep lit you are able to below the motor on transfer situation operate (for a brief time) and no electricity to entrance axle.
I've Chevy 2001 Blazer. The issue I'd is that I can’t switch on the 4Hi. So I went to dealership. The mend costed me $900 to exchange the TCCM.

I’m not fully confident what will cause the lights to simply blink and afterwards not go into gear. The 1st time I set the Blazer in 4Hi this Wintertime, it did just that…. I had to place it in neutral for it to go into 4Hi. Due to the fact then, it's going to shift on-the-fly. Why? I don’t know. There should be sensors both from the TC or perhaps the encoder motor to Permit it know when it's arrived at it’s supposed manner… I’d suspect it’s Component of the encoder motor, but I’m just guessing.
Kyle, you may put up as you like.So as to add information, my vendor was talking about replacing the two Pc modules affiliated with the 4wd, They mentioned same as if they changed them in ’05 that the two must be replaced at $1060 in addition tax and that was a mininum.
