I have a 99 blazer LS. It has a NP236 transfer case.I need to buy a motor for this
I removed old motor and it had 2 connectors on it. One was a 6 pin the other was a 4 pin. What motor and where can I get another one. Everything I see available online the pin connectors don't match up. Any help would be appreciated. I am new to this forum.

 

I have no experience with servicing the transfer case, however I can suggest the way I check if a part is correct or not. I used one of the online GM parts vendors that allows you to enter in the VIN of your Blazer. This ensures that the parts listed are correct for your vehicle. I like using this one: https://www.gmpartsgiant.com/

Good luck and be sure to report back on your repair and if you have any other questions.

 

No listing on that site for transfer case motor for my VIN. Thanks anyway

 

If you can find a salvage yard near you they'd be able to set you up, if used parts aren't your cup of tea you can call a Gm dealerships parts department and give them the VIN, they'll run it and tell you what you need. There were 4 options for that year if I'm remembering correctly.

 

GM 12474401 is the proper replacement shift motor for the NP8 (NV236/NP236) transfer case. Rockauto has a bunch of different options for your vehicle.
