Ive searched and cant find a solution to getting the light to go off even after I unplug it on the radiator. Do I need to unplug the RAP module for a few seconds or what? Thanks in advance. This is on a 94 z28.

 

Did you check the level sensor harness wires to make sure they are not shorted together?

 

Not shorted on the plug, but somewhere down the harness they could probably be shorted I guess.

 

Would there be any other reason for the light to stay on?

 

The latching relay is in the RAP module. Haven't heard of that going bad, but I suspect it's possible.

 

Thanks, I will probably check that out sometime this weekend.

 

Is the radiator full?Check it when its cold.Did you change out the fluid recently?

 

Radiator is full, I am sure the wires are shorted down the line somewhere, just have to find the time to check them.

 

This may help locate the short: Use a multimeter set to continuity with an audible beeper if available. Unplug the connector and connect the meter leads to each wire. Then move along the wire bundles wiggling them until the short becomes intermittent. You can do this without a beeper alarm if you use long leads and keep the meter positioned where you can see the display. Another tool to use instead is a battery-powered test light.

 

Thanks for the tip, it will give me something to do this weekend. Again thanks for all the replies.
