Two days ago i changed out my motor mount closest to the rear of the car ( dont know which one it is), and i had to unbolt my heater wire to get to the bolt, i got everything back up and going. This has nothing to do with it but all of a sudden today my temperature guage isnt working, Do you think i might have hit something while i was down there? i guess im wondering what i should do and if me fooling around with that heater wire maybe jarred something. LMK thanks HT
