My A/C is working, though not as good as it once did so I ran diagnostics and got a code of 46. after reset and continued operation the code 46 came back immediately. I have not found info on this code in past posts. Does anyone know what this code is and how to correct?


My car is a 2003 XKR Convertible.

 

If my diagnostic information is correct, it has to do with the Footwell Servo Drive Circuit. That is the electric motor that controls the lower vent. It said the possible causes could be 1 Open Circuit, 2 shorted circuit, 3 high resistance in the circuit, 4 Servo drive bad.

My experience with other vehicles, is the Drive servo is bad? The footwell door could be lodged somewhere and cause the motor not to move? I don't see how this would affect the coldness of the A/C .

 

Does anyone know the part number or location of this servo drive? Sounds like it could affect cooling and / or heating air flow out of their respective duct work. I am getting cold and hot air but seems like flow is not as strong.
