Can anyone explain to me what the different lights are for warnings on the '02 Chevy Mailbu? I am confused because there is one that looks like a box with an arrow point to water it flickered on then stayed off tonight and already my check engine light is on... I can't really afford to take it in so I was wondering what that meant so when I tell my dad i can explain what is going on (he lives 39 miles away from me)
