most likely in the air passageway. It's placed there so the air the motor blows keeps the resisters from getting too hot.
Remove the glove box. The front blower motor and the resistor can be accessed from there.
There is really no method to "check" the resistor, text by substitution.
A malfunctioning blower motor resistor will cause the blower motor not to work. When the resistor is bad the blower motors will not turn on.
The a/c heater blower motor resister is located in the vehicle on the passengers side inside the housing next to the blower motor...............Remove the blower motor resistor wire harness connector.Remove the blower motor resistor screws.Remove the blower motor resistor.
A bad heater blower motor resistor would effect one or more blower speeds other than high.
If the blower works on some speeds and not on others, you may not need a motor. Instead, you may only need a new blower motor resistor.
Resistor is a separate unit from the blower motor
Generally the blower motor resistor is found close to the blower motor. It relies on the blower motor to keep it cool.
Take it to a repair shop.
On the blower housing. Remove the glove box to gain access.
The blower motor resistor has failed.The blower motor resistor has failed.
