Keep air moving through your truck's heating and A/C system with the Four Seasons blower motor, part number 35546, a double-shaft, vented motor with CCWLE (counterclockwise, lead end) rotation. It fits many trucks, among them the 1990-2008 Kenworth C500, 1992-1993 Kenworth C540 and 1991 White/GMC WHM, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list.
Four Seasons brings more than 50 years of mobile A/C experience to this motor and builds it to compare with the factory unit:
- O.E. design and performance: designed to match or surpass the original equipment design and performance.
- Magnets: magnetic size and properties are comparable to or better than OEM.
- Windings: built to OEM specifications or better.
- Speed: motor RPM is equal to or higher than the OEM motor.
Blower wheel not included: this motor is supplied without the wheel. Transfer or replace the wheel as directed by the service procedure.
The blower motor drives the fan that pushes air through the heating and A/C system and out the vents. Signs it may need replacing include weak or no airflow, a blower that runs only intermittently, or squealing or grinding from the blower area. Switches, resistors and wiring can cause similar symptoms, so diagnose the cause before replacing the motor. Four Seasons says its products are engineered and tested with trouble-free operation in mind.
