My 03 crew started blowing the dash light fuse #18 radio has been in for a good month already, any electrical help would be great right now

 

If the problem did not start until after the radio install, might want to unplug the radio, and see if the fuse will hold.

Fair amount of diagrams in this thread :

Should be a quick test with the radio, as it is easy enough to get at.

 

pulled radio checked wires did a reinstall, fuse is holding on dim setting, thanks will keep an eye on it
