when you have a clicking noise on your passenger side of a 2000 Chevy Blazer and your transfer case is slipping

Will transfer module make truck feel like it slipping

 

Transfer case doesn't "slip" like with a clutch as much as engage/disengage. The transfer case control module (TCCM) located behind the passenger side kick-panel is what controls whether or not the transfer case is engaged. The TCCM uses relays installed on a circuit board that will click. When the TCCM goes bad, there can be lots of clicking sounds. An easy thing to try is to remove the kick panel and disconnect the electrical plugs and inspect the terminals and receptacles for corrosion. It is also not uncommon for the TCCMs to go bad and fail. People will get replacements at wrecking yards or they can be found as new-old-stock (NOS).

 

Do you have a 3-button or 4-button 4wd switch in the dash? When does it feel like it is slipping; while turning, driving straight, when in 4wd, and/or when in 2wd? Your post is a bit light on details that we can use to assist you.

This depends on the transfer case. The NV236/NV136 (4button or newer AWD) are equipped with a viscous coupling that is engaged to varying degrees of slip depending on conditions when in Auto4wd mode in the NV236. The NV136 is always monitoring conditions and adjusting the clutch load accordingly to reduce wheel slip. When in 4HI or 4LO in the NV236, this coupling is locked.

 

I stand corrected. Go by what swartkik says!
