Where is the Blower Motor Resister on a G20 Chevy Van?

The blower motor resistor on a Chevy G20 van is typically located under the dashboard on the passenger side, near the blower motor itself. You may need to remove the glove compartment or other panels to access it. It's usually mounted to the HVAC housing and connected with a wiring harness. Always consult your vehicle's service manual for specific details and diagrams.
