I was trying to pull out the instrument cluster and in the proceess I disconnected AC connector, clock connector, and connectors that are associated with the instrument cluster. After I installed the instrument cluster back and reconnected all the connectors everythings were working OK except the "OUTSIDE TEMP" indicator always show 41 degrees even outside feels like 20 degrees. What is the problem? Is there any way to calibrate it?

 

You might want to try the resetting of the computer by disconnecting the cars battery and leave it sit like that for about 30 mins. or so. When you reconnect the battery, the computer will have to re-learn everything about your car, possibly even the temp. sensor. Also, you might want to check that you have a good connection to the instrument cluster. If that doesn't work, try calling the dealer and seeing if they can re-set it for you, or replace it if it is broken.
