GMC C5500 Topkick Blower Motor and Related Products

ACDelco GM Original Equipment HVAC Blower Motor Resistors provide stepped voltage drops to provide multiple blower fan speeds and are GM-recommended replacements for your vehicle’s original components. This original equipment blower motor resistor has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Carquest Premium Blower Motors are engineered and tested to provide years of trouble free operation. Backed by over 50 years of mobile A/C experience, fix it once and fix it right with Carquest Premium Blower Motors. Meets or exceeds OE design. Magnetic size and properties compare or exceed OEM. Windings meet or exceed OEM Specifications. Motor RPM equivalent to or exceeds OEM motor.

GM Genuine Parts HVAC Blower Motors are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These HVAC blower motors are electric fans located in the HVAC housing. The fan pushes air through the heater core and evaporator and into the cabin. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

The blower motor assembly is designed to push/pull air across the A/C evaporator, aiding in heat transfer and regulating the vehicle’s interior temperature. A malfunctioning blower motor can lead to poor cabin cooling or heating and insufficient windshield defrosting, reducing driver visibility. When replacing a failed blower motor assembly, other HVAC system components should be checked for functionality as they can contribute to blower motor failure. The blower motor resistor and cabin air filters should also be inspected to ensure optimal performance. Our blower motors are manufactured from the highest quality materials and are engineered for long life under extreme conditions, ensuring reliable performance and durability.

Modern vehicles may have 100 or more electrical harness connectors in every operating system of the vehicle. Terminal tension may weaken with time or corrosion may occur within the connector housing making replacement necessary. When replacing any harness-connector assembly approved wire termination methods must be followed to ensure a successful and long-term solution to the original problem is made. A failed terminal connection, terminal corrosion or damaged wire will result in an electrical system fault.

The heating-ventilation-air-condition (HVAC) blower motor resistor is designed to control the speed of the interior blower motor. Older applications of this device consisted of 2-3 voltage resistor devices on a board while newer vehicle applications the device contains integrated circuitry and a heat sink to control the speed of the interior blower motor. Reducing voltage with a resistor will natural created large amounts of heat within the resistor block so the resistor will always be mounted in the vehicles ventilation system very near the blower motor itself so that the moving air may cool the resistor assembly. The common failure mode of this device is the loss of one or all speeds of the blower motor. When replacing the unit, the blower motor running amperage should be verified along with the incoming airflow to the heater system. If the incoming air passage should become blocked with leaves or debris, or, on certain vehicle application, should the cabin air cleaner become blocked impeding the movement of air into the cabin, the resistor will overheat and fail.
