Description of Surwit HVAC Blower Motor Control Module Resistor Kit with Harness for Chevy Silverado Tahoe Trailblazer GMC Sierra Envoy Yukon XL - Part# 15-81773 RU-631 89018778 89019351
The blower motor resistor is an electrical component that is a part of the vehicle's heating and air conditioning system. It is responsible for controlling the blower motor’s fan speed. When fan speed is changed via the knob on the instrument cluster, the blower motor resistor changes setting, which changes the speed of the blower motor. This blower motor resistor fits for Chevy: 2003 - 2006 Silverado 1500, Silverado 1500 & 2500 HD, Suburban 1500 & 2500, Tahoe, Trailblazer EXT, Avalanche 1500 & 2500, 2007 Silverado 1500 & 2500 HD Classic, Silverado 3500 Classic, 2003 - 2004 Silverado 2500, 2003 - 2009 Trailblazer, 2004 - 2013 Impala, 2014 - 2015 Impala Limited, 2004-2007 Monte Carlo. For GMC: 2003 - 2006 Sierra 1500 & 1500 HD Envoy XL Yukon & Yukon XL 1500 & 2500,2007 Sierra 1500 & 2500 HD Classic Sierra 3500 Classic. This blower motor resistor fits for GMC: 2003 - 2004 Sierra 2500 & 2500 HD, 2003 - 2009 Envoy, 2004 - 2005 Envoy XUV. For 2003-2004 Oldsmobile Bravada, 2004-2008 Pontiac Grand Prix, 2004-2007 Buick Rainier, 2005-2009 Buick LaCrosse, 2005 Buick Century, 2005-2010 Buick Allure, 2003-2006 Cadillac Escalade & ESV, EXT. Replace Part Number:1580567, 1581773, 1711975, 19260762, 52409643, 52413530, 52495874, 89018964, 89018778, 89019351, 93803636, 15-80567, 15-80906, 18-81773, JA1639, RU-631. As the fan speed is one of the most frequently adjusted settings of the air conditioning system, the blower motor resistor is put under constant stress, which can cause it to eventually fail. A failed blower motor resistor can cause issues with the operation of the entire heating and air conditioning system. A bad or failing blower motor resistor will produce a few symptoms: Blower motor stuck on one speed; Blower motor does not work on certain settings; No air from the vehicle’s vents. As the blower motor resistor is the component directly responsible for powering the blower motor, when it fails it major issues with the blower motor and the heating and air conditioning system can be experienced, Please replace your blower motor resistor in time.
