I have a 98 T&C Lxi that has a problem at 50 MPH+. The outside temperature reading varies widely at highway speeds. It can vary by a range of 40 degrees and changes in 4-5 degree increments every 2-3 seconds. At lower speeds, the temperature readings are stable and appear to be correct. I suspect a loose sensor connection; however this problem started after the clockspring was replaced (coincidence?). Any ideas out there and can anybody tell me where the sensor is physically located. Thanks Kevin
