2000 Jimmy Outside Temperature Display is off

Why is my 2000 Jimmy S15 SLE Outside temperature display (not the engine temp) always 5-8 degrees too hot?

Mine is way off, sometimes it is hotter, sometimes it is colder, like really colder

My 2000 always reads about 4-6 degrees too hot, too. Any way to calibrage it?

According to my Stealer, there is no way to re-calibrate it, and no one in this Forum has come up with a way to calibrate it.
