Pontiac Repair: warning lights, hight temperature, pontiac grand prix

Question
I have a 1990 Pontiac Grand Prix and the warning lights for low gas level and high temperature are always on all the time even when the car is full of gas and the temperature is normal. What part of the system is faulty and could the repairs be done at home?

Answer
Hi, no the hight temperature sensure you can change this just replace the sensure. IF the gas gauge is working, then it would go to the light circuit has a break in it. the hight temperature you can change. the level light let a repairman check it out.
