2010 GMC Sierra 3500 HD Blower Motors

Genuine GM blower motors for the 2010 GMC Sierra 3500 HD, at wholesale prices. Blower motors and resistors split on whether the vehicle has manual or automatic climate control. One-ton heavy duty truck in single and dual rear wheel and chassis cab form.

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.

What sets these apart

• 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.
• OEM, not lookalike. With blower motors the difference shows up on installation day, not in the photo.

Avoiding the wrong part

Genuine GM parts carry the factory part number, so supersessions are documented rather than guessed at. Run your VIN first. One vehicle can list several nearly identical parts and only one is correct. Because we ship centrally, a heavy part costs less delivered here than from a coastal seller.
