2004 park avenue thermometer not reading correctly. outside temperature is reading too high. displays outside temperature on a/c control display.
I would guess the outside thermometer has lost its calibration.
Does it seem consistently 5, 10 or 20 degrees off all the time?
Let me know.
Regards,
I would suggest replacing it. It is a very simple circuit and not very much to go wrong. You will find it is a (2) wire connection and a small thermistor located in the front, center, upper area of radiator near the hood latch area.
Good luck, let me know.
Regards,

Replace the sensor near the hood latch, I had the same problem. It also kept my AC from working.

It seems about 20 to 25 degrees off. This morning it was in the mid 70's and it was displaying around 100. We are in the mid 90's now and it is displaying 110. I think 110 is as high as it will read. We have noticed that the accuracy has been degrading over the last few months.
