Welcome! My name is ***** ***** I will do my best to assist you with this problem.
I am sorry for the long wait
is this the inside fan still running when the car is off ?
Customer: replied 2 years ago.
yes
Expert:  Gary replied 2 years ago.
thank you for that information
99 % of these that the inside blower motor will run with the key OFF are bad blower motor processor / resistor assembly internally stuck on
the fix for this is to replace the blower motor processor which is located right next to the blower motor and most auto parts stores sell them and very easy to change

is that the same as the blower resistor. which i understand has to be changed inside the car not from under the hood
Expert:  Gary replied 2 years ago.
that is correct
its sometimes called the resistor or a blower motor processor
correct inside the car under the passenger side of the dash right next to the blower motor just like i picture i sent you to cut and paste for the exact location of it
Customer: replied 2 years ago.
so your picture is from the inside and not from under the hood. I glanced at it and thought that it was from under the hood.
