【UPGRADED THERMAL & ELECTRICAL STABILITY】Built with heat-resistant components and reinforced circuits, this blower motor resistor module withstands high HVAC temperatures and continuous load. Provides reliable long-term performance and reduces repeated blower resistor failures 【RESTORES CORRECT FAN SPEED CONTROL】A failing blower motor resistor often causes the fan to work only on high or lose multiple speed settings. This upgraded HVAC blower resistor restores proper low, medium, and high blower motor speeds, ensuring stable airflow for heating and A/C 【VEHICLE FITMENT 1】2002-2006 Chevy Avalanche 1500 / 2500,1999-2006 Chevy Silverado 1500,2007 Chevy Silverado 1500 Classic,2001-2003 Chevy Silverado 1500 HD,2005-2006 Chevy Silverado 1500 HD,2007 Chevy Silverado 1500 HD Classic,1999-2004 Chevy Silverado 2500,2001-2006 Chevy Silverado 2500 HD,2007 Chevy Silverado 2500 HD Classic,2001-2006 Chevy Silverado 3500,2007 Chevy Silverado 3500 Classic,2000 Chevy Suburban 1500 5.3L,2000 Chevy Suburban 2500,2000-2002 Chevy Tahoe 【VEHICLE FITMENT 2】1999-2006 GMC Sierra 1500,2007 GMC Sierra 1500 Classic,2001-2003 GMC Sierra 1500 HD,2005-2006 GMC Sierra 1500 HD,2007 GMC Sierra 1500 HD Classic,1999-2004 GMC Sierra 2500,2001-2006 GMC Sierra 2500 HD,2007 GMC Sierra 2500 HD Classic,2001-2006 GMC Sierra 3500,2007 GMC Sierra 3500 Classic,2000-2002 GMC Yukon,2000-2002 GMC Yukon XL 1500,2000-2002 GMC Yukon XL 2500,2002 Cadillac Escalade,2003-2005 Cadillac Escalade EXT 【OE PART NUMBERS】89019089, 973-409, 973409, 22807122, 15305077, 15-81087, 89018597, 1581087, RU371 【EASY PLUG-AND-PLAY INSTALLATION】 This blower motor resistor replacement features OEM-style connectors and mounting points for quick installation.
