Hi there, I am cam. Which temp sensor did you replace?
Ok, what does the outside temp show in the dash?
And what does it show? IS it correct for the actual temp outside? And is the fan in the sensor in the roof running?
Ok, lets try a reset. Take the battery cables off the battery, hold the ends together for 10 seconds then attach them to the battery and see what happens. This will reset the whole vehicle.If you have 2 batteries, then remove both and touch only one set.
