Kind of off topic, but I can not seem to find a post which fits as well as this one. I have an 88 C1500 that has one of the instrument lights come on. Unfortunately the label is basically destroyed so I can not tell what it is supposed to be telling me. The only code it is giving is voltage on the coolant temp sensor, but that makes the check engine light come on, which is a different light. The exact light that is on is the one that is on in the top picture that burkey05 posted in the second post on this thread. I have been searching Google for an hour now and that is the only picture I can even find which is the same instrument cluster that this truck has, but unfortunately it is too blurry for me to read what it says it is supposed to be. Can anyone please help me figure out what that particular light is supposed to be?
