My daughter complained of poorly performing AC today. I rode in her car, and yes, it's not working correctly, BUT it's not the AC, it's the blower fan speed - always slow.
Patient vehicle is a 2006 9-5 SC with Sport Package. It has about 136K miles, and mostly in very good condition. The AC is refrigerating properly, but the BLOWER MOTOR runs one slow speed no matter what the fan speed control is set for.
I'm familiar with how the blower motor regulator dumps power to a resistor, but I've normally seen the fan going full blast when there's a failed circuit. The symptom of one slow speed is one which I haven't been able to get much traction on by Google search or searching the SAABnet board.
Any help appreciated.
