Q: How do you remove the blower unit on a Toyota Prius?
A: To remove the blower unit from 2001 through 2003 models, start by checking the fuse and connections for looseness and corrosion. Then, remove the glove compartment door and cut out the reinforcement bar. Slide out the PCM and remove the blower assembly, cabin air filter, and blower motor controller. Disconnect the wiring from the motor and remove the motor mounting screws to lift off the motor. For 2004 through 2009 models, remove the lower instrument panel and interfering computers, disconnect and label the 10 connectors, and remove the blower unit and air inlet servo. Detach the wiring harness from the blower motor and remove the motor with the fan attached. For 2010 and later models, release the claws and detach the lower cover, disconnect the wiring from the blower, and remove the blower unit with the mounting screws. Installation is the reverse of removal, but be sure to recheck all connections before reinstalling the instrument panel.
