How to troubleshoot a non-functioning blower motor in Toyota Sienna without Automatic Air Conditioning?

For models without Automatic Air Conditioning, if the blower motor isn't functioning, begin by checking circuit connections for looseness or corrosion, ensuring the battery is fully charged, and inspecting the Heater fuse and blower relay in their respective locations. Test the blower motor relay for proper operation and replace it if it fails. With the transmission in Park and the parking brake engaged, turn the ignition switch to the ON position. Then, switch the heater controls to FLOOR and the blower speed to 4 while listening for blower operation; repeat this for all blower speeds. If the blower doesn't operate, and you've verified fuses and relays, proceed to test the blower. Locate the blower motor's electrical connector and back-probe the Blue/red wire terminal to check for at least 10 volts with the mode switch on any position other than Off and the ignition switch On. If voltage is absent, investigate the circuit from the fuse panel to the control panel or from the control panel to the blower. If voltage is present but the blower doesn't work, backprobe the Black/White wire and connect it to a known good chassis ground using a jumper wire; if the blower operates, replace the blower motor, otherwise, check the ground connections between the blower resistor, blower switch, and ground (White/Black wires). If the blower functions but not at all speeds, inspect the blower resistor located on the blower housing beneath the center of the dash; visually check for damage or use an ohmmeter to test its resistance values and replace if necessary. If issues persist with blower speed variations, remove the heater/air conditioning control panel, disconnect the electrical connector from the blower speed switch, and test the terminals for continuity, replacing the blower speed switch if continuity is not as specified.

How to remove and install a blower unit in a Toyota Sienna?

Disconnect the negative cable from the battery. The blower unit is located in the passenger compartment above the right front footwell. Remove the right lower dash panel. Remove the three bolts and pull the ECM out of the way. To remove the blower, remove the blower unit retaining screws and lower the unit from the housing. If the motor is being replaced, transfer the fan to the new motor prior to installation. Installation is the reverse of removal. Check for proper operation. Depending on whether you have a four-door or five-door model, remove the rear seats and either the left or right rear quarter panel trim. Five-door models have two rear blowers, one for heating and another for air-conditioning, mounted in the right rear quarter. On four-door models, disconnect the electrical connector, then remove the three blower motor mounting screws and the blower motor. On five-door models, once the rear heat unit has been removed, remove the air-mix motor, then remove all the screws of the unit cover. Flip the cover over and remove the blower fan, then flip the cover back over and remove the three blower motor mounting screws.

Toyota Sienna Blower Motor

The Blower Motor in Toyota Sienna cars works under the heating and air conditioning system to regulate the amount of air to be circulated in the car. Through variation of the blower motor controls, drivers can be able to control the temperature inside the car, in the event of a cold morning, the windows are frosted and so the driver blows hot air or in a hot day where a driver would blow cold air into the car. The blower motor controls are mounted on the module and wiring for convenience, and they can be operated easily. Nonetheless, problems in the electronic module or wiring could develop that cause failures and subsequently, the capability of controlling the heating and air conditioning is lost. Any issues associated with the blower motor controls should be rectified without any delay to allow comfortable driving.

Toyota Sienna Blower Motor Parts Questions & Experts Answers

Motor Sub-Assy, Blower W/Fan
87103-08050
Q: How to troubleshoot a non-functioning blower motor in Toyota Sienna without Automatic Air Conditioning?
A: For models without Automatic Air Conditioning, if the blower motor isn't functioning, begin by checking circuit connections for looseness or corrosion, ensuring the battery is fully charged, and inspecting the Heater fuse and blower relay in their respective locations. Test the blower motor relay for proper operation and replace it if it fails. With the transmission in Park and the parking brake engaged, turn the ignition switch to the ON position. Then, switch the heater controls to FLOOR and the blower speed to 4 while listening for blower operation; repeat this for all blower speeds. If the blower doesn't operate, and you've verified fuses and relays, proceed to test the blower. Locate the blower motor's electrical connector and back-probe the Blue/red wire terminal to check for at least 10 volts with the mode switch on any position other than Off and the ignition switch On. If voltage is absent, investigate the circuit from the fuse panel to the control panel or from the control panel to the blower. If voltage is present but the blower doesn't work, backprobe the Black/White wire and connect it to a known good chassis ground using a jumper wire; if the blower operates, replace the blower motor, otherwise, check the ground connections between the blower resistor, blower switch, and ground (White/Black wires). If the blower functions but not at all speeds, inspect the blower resistor located on the blower housing beneath the center of the dash; visually check for damage or use an ohmmeter to test its resistance values and replace if necessary. If issues persist with blower speed variations, remove the heater/air conditioning control panel, disconnect the electrical connector from the blower speed switch, and test the terminals for continuity, replacing the blower speed switch if continuity is not as specified.

Q: How to remove and install a blower unit in a Toyota Sienna?
A: Disconnect the negative cable from the battery. The blower unit is located in the passenger compartment above the right front footwell. Remove the right lower dash panel. Remove the three bolts and pull the ECM out of the way. To remove the blower, remove the blower unit retaining screws and lower the unit from the housing. If the motor is being replaced, transfer the fan to the new motor prior to installation. Installation is the reverse of removal. Check for proper operation. Depending on whether you have a four-door or five-door model, remove the rear seats and either the left or right rear quarter panel trim. Five-door models have two rear blowers, one for heating and another for air-conditioning, mounted in the right rear quarter. On four-door models, disconnect the electrical connector, then remove the three blower motor mounting screws and the blower motor. On five-door models, once the rear heat unit has been removed, remove the air-mix motor, then remove all the screws of the unit cover. Flip the cover over and remove the blower fan, then flip the cover back over and remove the three blower motor mounting screws.
