Four Seasons 75781 blower motor for the 1986-1997 Peterbilt 357 and other vehicles spins the blower wheel that pushes air through the heating and A/C vents. It is backed by over 50 years of mobile A/C experience.

  • Engineered and tested for years of trouble-free operation
  • Design and performance meet or exceed O.E.
  • Magnet size and properties compare to or exceed OEM
  • Windings match or exceed OEM specs
  • Motor RPM is equivalent to or above the OEM motor

Weak airflow, no air at some or all fan speeds, or noise from the blower can mean the motor is wearing out. A blower resistor, a blown fuse or damaged wiring can be behind the same signs, so find the cause before you buy a new motor.

It also fits the 1989-1993 International 8300 and the 1981-1987 Mack Marmon.
