The Four Seasons blower motor, part number 35674, is a double-shaft, closed motor with CW/CCW rotation that drives the blower wheel moving air through your truck's heating and A/C system. It fits many vehicles, among them the 1989-1999 Kenworth T400, 1988-1990 Kenworth C540 and 1987-1994 Kenworth T800. See the "Vehicles it fits" section for the full list.
This motor is supplied without the blower wheel. Transfer the wheel from your original motor, or replace it, as the service procedure directs. Four Seasons engineers and tests each motor and draws on more than 50 years of mobile A/C experience.
- O.E.-level design: meets or exceeds original equipment design and performance.
- Magnets: magnetic size and properties compare to or exceed OEM.
- Windings: built to OEM specifications or better.
- Motor speed: RPM equal to or greater than the OEM motor.
Signs a blower motor may need replacing include weak or no airflow from the vents, a motor that runs only some of the time, or grinding or squealing from the blower area. Switches, resistors and wiring can cause similar symptoms, so diagnose the cause first. If the motor itself has failed, this Four Seasons unit replaces it.
