Fuse keeps blowing

So. before I start digging for this problem, I'm throwing it out there to you guys to se if there is any insight. My #14 fuse is intermittently blowing and I'm assuming that it's electrical related (loose wire/ground). The #14 fuse controls the interior lights and the window switches. I am thinking that it has something to do with the wiring going through the door harness and that is probably where I will start after checking for loose grounds. Anybody have any experiences similar to this, and what have you done. Help is greatly appreciated!

Loose grounds don't blow fuses - active cut/chafed/broken wires contacting vehicle ground do.

May as well start yer inspection where the passthoughs are - it's where the wires move the most.

Would help to determine what activity actually blows the fuse - help ye to narrow it down some.

BTW Fuse # 14 says:

14 15A Battery Saver Relay, Interior Lamp Relay

Yes, #14 is labeled as such, but it does affect the window switch when it blows. I'm thinking that it's the harness running through the drivers door as it most obviously sees the most "work" through the opening ad closing of the door on a constant basis
