Secondary water pump operation
I have noticed my secondary water pump is on whenever the key is in position one at all times even when the heater fan is off and both heater temperature controls are in the off position. BTW, the driver's side temperature control is all way to the off (blue) position which should turn both sides of the car temperature control off.
Is this correct? TIA
