S-10 / Blazer / Jimmy 4WD Transfer Case Control Module – Blue Plug – 98-05 – 15741322

Here’s a solid, used transfer case control module for your Chevy S-10, GMC Jimmy, or Blazer from 1998 to 2005.

It’s the part that lets you shift in and out of 4WD.

This one is in excellent condition—the seller notes it’s super clean with no corrosion and was pulled from a running vehicle, so you know it works.

The plug on this module is blue, which is the right color for many of these models.

The manufacturer part number is 15741322, and it also crosses with 599-100.

It’s a genuine General Motors part, not some off-brand replacement.

It’s a used part, but it’s been well taken care of.

If your 4WD isn’t engaging or you’re getting blinking lights on the dash, swapping this module out might just do the trick.
