blown fuse on 03 bonneville interior lights

Help. I keep blowing the fuse on my interior lights and have replaced the relay for the lights also. I took it to the dealer ( my warranty is about to run out) and all they did was place a larger fuse in it and it blew also, they said the only thing else to do was tear the interior out and check the wiring. Has any one had this problem and has another possible solution.

Thanks

Let em do what they have to!

I am still having the same problem. The interior lights fuse blows. Sometimes I replace the fuse and it will go for 4-6 months. Then I will have to replace it daily or weekly for a month. Then it will not blow for another few months. Has anyone had this problem and where did you find the problem? Also, where can I get the wiring diagram without buying the entire book?

Thanks for the help!

You can get pretty good WDs at the following website:

There are a couple ground busses you might check and clean, then use dielectric grease on during reassembly.
They are by each front door below the carpet. The buss is usually taped to a large wire loom that runs along the rocker panel. Each buss is very near the front of each front door.

Check this link to see pics of where these busses are.
