Question about 1989 Volkswagen Jetta 2 Door
WATER TEMP LIGHT FLASHING ALL THE TIME?
First check the coolant level in the reservoir.
If not low then you have an electrical issue. Remove the sensor connector from the top of the reservoir. Put a jump wire between the two connectors. Turn the key of on and hold for a few seconds. The light will always flash for a few seconds. It should go off. If it does the sensor is not working (unusual).
Sensor not working - unscrew from top of reservoir. It may just need cleaning of the two wires. If not replace.
If the light did not go off it is a wiring issue. There is a bared or broken wire. You will need to find the break.
