I tried searching the site to see if this question was asked before and I didn't see it so I thought I would give it a try. For a while now my cars temp gauge located on the review mirror will say SC located under the compass. I have no idea what this means and I did not see anything relating to this in the owners manual (but I wasn't expecting to find anything in there anyway). The temp has been acting up too. Some days it seems like it is working perfectly and others it will tell me that it is 117 degrees outside, there is no rime or reason for it. The temp does seem like it works more so than when it doesn't. Thanks and I hope someone has a solution to this that is not expensive which is what I'm thinking it will be to fix the situation.
