Q A Toyota Sienna Radiator Fan Fuse Wiring Diagrams Fuses look fine. 2. fan motors work fine (connected them directly to power source) 3. replaced the control module (attached to the radiator) 4. checked the temperature switch with ohm meter seems to be fine, resistance changes with temperature changes. jumped the plug that plugs in the temperature switch to rule out the switch, no fans. Pull the main#1 relay and check for voltage in hole 1. customer. i don't know if this will help but in an effort to get the fan on i removed the relay (fan 2) and put a jumper wire to the hot side of the radiator plug. the fan still did not come on. i energized the fan with my battery charger and it worked fine.
