My thermometer in the Blazer reads dependably two degrees

is 76. I don't know of any calibration for my Blazer. Maybe
your weather station has a tweak some where for fine tuning.

Where are you that the radio station keeps their thermometer in your
car?
Did you give them permission to install it, or did it come that way
from the factory?
