My interior lights always worked, the other day I sprayed out the engine bay without covering anything. Now my interior lights still work but they are really, really dim. What could I have done to the lights?
Do you

Hi,

There really isn't anything under the hood that is for the interior light. If you look at the wiring schematic below, it shows only one fuse under the hood that powers the parking lamps and interior lamps. If you sprayed on the fuse box, check to make sure the fuse is still tight, dry, and free of corrosion.

Note: I had to cut the schematic in two so you could read it. I did overlap them so you can follow from one to the next.

Pic 3 shows the fuse location in the under hood fuse box.

When you are checking, confirm that the headlamps and parking lights are all working properly.

Take care,
