1994 z28 all stock. My low fluid light comes on and mostly stays on and on top of that my temp gauge never mover from cold position.

I know it it not low on fluid and the heater blows warm air so Im wondering which of the many electrical widgets I need to steal from my parts car.
Thank you

 

test the temp gauge sensor, (number 20 on the list here 4th Gen LT1 F-Body Tech Aids ) should be on the driver side head by the number 1 spark plug. also if the low level light is the coolant light check the connection for the coolant level senor and test. (numbers 12 13 14 on same list) if its the low oil level light then check the the connections for the sensor, its on the driver side of the oil pan.

 

Thank you. its not raining today so I have a reasson to get outside now.lol
