The fuse for the courtesy lights keeps blowing and I can't figure out why. It is particularly annoying because it is tied to the radio, the trunk release, and the remote door locks. I have a 15A fuse in now but I know its just going to blow again. Anyone ever had a similar problem or any thoughts on a trouble shooting procedure.

 

The courtesy fuse powers a lot of stuff.

Keyless entry module
mirror lamps
radio
dome lamp
glovebox lamp
console lamp
audio alarm module under the steering wheel
theft deterrent module
instrument cluster
hatch release relay

Guess you have a chafed wire or a bad component. Could even be a bad bulb. It's just goint to take some poking around.
