I have 54 plate Vauxhall Astra 1.6 Club. 5 door.
About a year ago the information screen inside the car started showing that the outside temperature was slowly going up each day despite it getting colder outside. It now shows 69.5 degrees CENTERGRADE.
How do i fix this, has a fuse gone or is there a sensor that is broken somewhere, if so where is it. ??????
