Hi all ,I've had blower motor and resistor replaced but when I turned off the ignition switch, blower motor continued running. I'm aware that the relay can cause this but I cannot find the relay. My a/c is auto climate control and does not have the relay mounted on the firewall anywhere. Btw, I forgot to mention that when I disconnect the ground from the resistor, the blower shuts off after the fact of turning the ignition off.
