Our LCWRGS Heater Blower Models Compared
LCWRGS offers two targeted models in this category, each tailored to distinct model years for optimal fitment.
The first model replaces #700100 and fits 1997-2000 Chevy Silverado, Suburban, Tahoe, GMC Sierra, Yukon (1500/2500, C/K series), and Cadillac Escalade. It's perfect for older GM full-size trucks experiencing blower failure due to age or electrical issues. This unit delivers robust torque for heavy-duty use, with a focus on durability in high-mileage vehicles.
The second model, replacing #700191, targets 2003-2006 Chevy Silverado (1500/2500), Suburban, Avalanche, GMC Sierra, Yukon, and Cadillac Escalade. Designed for newer platforms, it incorporates updated connectors for easier swaps and enhanced efficiency to handle modern HVAC demands. Both share LCWRGS's signature quality, but choose the 700191 replacement if your vehicle has the later square connector style.
Comparing the two: The 700100 model suits pre-2001 chassis with round connectors, while the 700191 excels in post-2002 models for better integration with updated dash designs. Both provide identical airflow ratings, but the newer one runs slightly quieter thanks to refined bearings.
