Does anybody on here knows where is the blower motor relay on a 91 civic hatchback si? i need to know so i can test it and finaly have some heat in my car cuz is getting very cold over here

 

If you remove the glove box, you will see where the blower motor is. If you look, you will see a black plug with wires going into it, that is the relay. You might want to check your blower motor first. Just my 2 cents
