Hi, my ECT light has stopped working, or maybe the ECT is not working, how would I know if it is just the bulb or the ECT is not activating. And, when the Turbo is engaged should the green light on the dash be lit? mine only lights up when I am about to start the engine. Please help.

 

Does the ECT light come on when you start it? If not, it's the bulb. Don't know about the green light for turbo. Do you have a turbo diesel? What is your rig?

 

Thanks, the ECT does not light up when I am starting, so it may be the bulb. I have a 92 ssrx turbo diesel. The light for the 4 wheel drive also does not light up, but the 4 wheel engages.
