Yeah, bad wiring sounds like.Tempeature gauge Problem:
I just found out!
so im driving down the street.
average speed 35-50
gauge reads normal temp.

when i use either blinker or Lowbeams the gauge goes CrAzY!
So...the car is not overheating but instead bad wiring ?
Thats just my extremely novice conclusion

wuznt sure if it matterd. left it off 4 30 min. and light still came on after 10 min of driving
