Hey guys, new to the group, I have a couple F-3550s but my personal one is a 2003 4 door dually with the Lariat package, 7.3 automatic 625,000 miles on original tranny, bought it new. Great truck but having some electrical issues with it now. When I turn on my overhead with the push button in the ceiling the light comes on then immediately goes out and my windows wont work and radio wont work. When I turn it back off the windows and radio will come back on after a while. I believe it is tied into the delayed entry but cant seem to find any info on what is causing it, short, bad ground, etc. Any suggestions. Thanks

I've got the same issue in my work truck. 2002 SCLB 2wd 7.3 4r100 311K miles. The company isn't interested in spending any time on this old thing so I just live with it for now. It took me some time to get used to. I can't pattern the issue so I'm not sure where to look but, I'm leaning in the same direction as you.

Good to hear from you 5j's, after searching a bunch of different forums and websites I decided to take the steering column apart, low and behold one of the small wires going to the overdrive button was bare and shorting out, fixed that and so far so good except for the radio not coming on. If I hit the dash right above the instrument cluster it well come on. According to what I have read the whole issue is with the instrument cluster being bad. Apparently there is some type of relay for the acc. delay built into the cluster itself and these go bad with age. The only fix is to have it sent off and be repaired or find one from a like vehicle and replace but then you have to get odometer redone which should not be a big issue. If I am not mistaken ONLY year models 2002 an 2003 with the 7.3 will work. Also a lot of people were telling me the gen module was bad, our year vehicle does not have a gen module, but instead have a VSM I am assuming Vehicle Security Module. On my 03 it is behind the big brace behind the radio on the inside firewall right under the windshield, a bugger to get to. Try hitting the dash and see if that works, I know it sounds kinda redneckish but if it helps to figure out what is wrong so be it, lol.
