Couple of quick questions, I've a light out idiot light but can't find any lights out, I do have a blank on my right rear taillight could that be it and my 3rd brake light works when it wants to and doesn't other times for days on end. Second what size are the sedan rear deck speakers, the previous ow er glued the covers down and I don't want to rip the glue up until I've the right speakers tp replace the blown ones.
