The heater blower does not work and I need to check the relay and switch and don't know where they are located.

Hello,

An inoperative blower motor can be due to a bad relay/wiring, faulty blower motor resistor or a bad motor.

The front blower motor relay is located in the fuse box, in the engine compartment.
The front blower motor resistor is located in the engine compartment on the inboard side of the heater-A/C housing (see diagram)

I have attached diagrams for your reference.

Please let me know of any questions.
Thank you.
