A while ago I had some a/c work done at the dealer and since the out door temp has been acting strange. For instance, today the temp is 94 and the display says it's 77. Usually after a few miles it displays the correct temp. I suspect the connection was not made correctly when the tech was under the dash.
Is there any way for me to check without tearing the dash apart?
Thanks

 

the outside air temp sensor is infront of everything by the grille
