Okay guys I have no freaking idea how to access the light behind my heater assembly. I need to get the blue filter out so I can put a red bulb in so it matches the rest of my guages. Also if anyone happens to know what kind of bulb is used in it that would be helpful to. Is it a 194 like the dash cluster? Thanks guys I have found the wire that goes to it and everything but I don't know how to go about getting the bulb out and replacing the filter.
