Got owners manual? Is it set to the right scale? ----- Well i checked 20°C = 68°F so that ain it. Does it change at all? No big deal to some but i like my stuff to work too! It has a sensor prob. behind the grill that can be changed if needed. Check manual, or try unhooking neg batt. cable for a min. That's all I know. Never had a problem with one. Might be able to scan test body control module to read data. Compass working? Post results when fixed.
