The other day i noticed that the outside temperature display seemed to be warmer than it was actually was. now it is stuck on 127 when it is only 75 outside. i checked all of the fuses in the front and the back and found that the fuse for ELEC was blown. i replaced it and it worked for a couple of minutes and the display reading started to adjust. then it blew the fuse again. then there was a message to service engine soon, and that the volts were high!!! any ideas
