The fan runs at constant speed, will not turn off with car. Must un plug fan to make it stop running. Climate control system does not make any differience what it is set at. Ie Auto Hi Auto Low, Auto all the same. What could be the problem?

Do you

Either the ECC (Electronic Climate Control Unit) or the Blower Control Unit. I would probably start with the Blower Control Unit, It is basically the old fan speed resistor
