This sounds to me like you could have a problem with the map light switch. In the diagrams down below I have included the wiring diagrams for the interior lighting circuits for your vehicle. I would look for a short to power in the map light switch and would recommend replacing the whole assembly. This is due to the fact that there is still power to the light even when it is switched off, as it still has a dull glow. A ground problem would also cause a dim bulb, but only when it was switched on. Please go through the diagrams down below and get back to us with what you are able to find out.
