I have the fancy a/c, Problem the heater blower motor remains on high, the only speed I get, all the time. even when the car is shut-off and key out off the ignition. The blower relay should be on the firewall beside another relay, on the relay rack, but I have only one relay. Which I think is a/c pressure relay. It is not the common relay connector end which is used for the horn and other similar relays.
I can only stop the blower if the wire is removed from the blower motor. Or if I remover the connector fron the air temperture sensor down stream of the blower in the haeter duct below the delay rack. the temperture sensor is eletonic, not like the old type that had 3 differeny coils to sense temperature. Could the ingition switch still send power to the motor or is it the climate controll head?
