01 XC70 85k miles.
Have intermittent outside temperature reading issues. Seems to have occurred when the weather got warmer here but not sure since it is fairly intermittent.
Called dealer for parts and found there are 2 outside sensors, one in each side mirror. Used my BSR PPC Volvo code reader and got no codes related to ambient sensor.
Have any ideas on how I can isolate which side is failing? As luck would have it, the parts are different for each side. Maybe I have to wait until it fails more frequently
