I purchased my F150 new in late '01 and it has the compass and ambient temperature reading in the console between the visors. The temperature reading was always quite accurate until a few months ago when I noticed that it started reading about 10 degrees higher than the actual temp. Not when I was sitting in traffic or when I first started the truck (which can be normal), but pretty much all the time. I called Ford and they wanted $115 to "diagnose the problem" plus whatever it would cost to fix it.
Instead, I located the sensor (in front of the radiator) and cleaned it off, hoping that would do the trick. Well, it still reads about 10 degrees high. I thought about replacing the sensor myself and the cost of a new one is $100, which i will pay if that is the problem. Does anyone know if there is anything else I should do or check before dropping the $100 and replacing the sensor? Please let me know.
THanks!
