2012 GMC Sierra 2500 HD Blower Motors

Genuine GM blower motors for the 2012 GMC Sierra 2500 HD, at wholesale prices. Blower motors and resistors split on whether the vehicle has manual or automatic climate control. GMT900 HD through 2014, K2XX HD from 2015 to 2019, and the T1XX HD from 2020.

When to replace

Fan that only works on high, or no airflow at all. On a heavy duty pickup, cab configuration, drivetrain and box length all split this group, so the badge on the tailgate is not enough to order from.

Why order factory

• VIN verified fitment. We confirm the blower motors number against your vehicle before it ships.
• Same day dispatch. Order blower motors by mid-afternoon and it leaves our warehouse that day.
• Returns without a fight. We would rather fix a blower motors order than argue about it.
• Covered by GM. On blower motors that coverage is worth more than the price gap.
• Real wholesale. The same blower motors your dealer sells, at a fraction over our cost.

Avoiding the wrong part

The factory number ties back to GM engineering records, which is something no aftermarket catalog can offer. Give us the number stamped on the old part and we will trace what it superseded to. Same day shipping on in stock items, direct from one of the largest GM parts warehouses in the country.
