03 f150 electrical problems
i have a 2003 f-150 2wd with the 4.2 motor and have recently been having problems with some electrical things. about 2 years ago it had a new fuse box installed. now this year ive been having other problems like after the truck is turned off the fan for the heater will keep running and the running lights and tail lights will stay on until i disconnect the battery.
anybody have a clue about what could be the problem? possibly the new fuse box or a relay?

From: Back where I started...
I'd have to look at a wiring diagram to see where those circuits would have a common point, but one thing (especially if you've already had to replace a fuse box once before) is the windsheilds leak water into the CJB/GEM module (interior fuse box) under the dash, driver's side. All kinds of demons come out when the box/module gets water in it.

the truck was in an accident back in 2004 and when they replaced the windshield but when they replaced the fuse box they checked for all kinds of leaks with a smoke machine and found no leaks to how it could of gotten wet. i looked but could not find a wiring diagram for myself.
