cruise and horn wont work 03 f350 crew cab 4wd 6.0


Asked by vsa2 Jul 26, 2010 at 02:48 PM about the 2003 Ford F-350 Super Duty Lariat Crew Cab SB 4WD

Question type: Maintenance & Repair

I just purchased an 03 F350 4wd crew cab Harley Davidson edition with a 6.0 diesel. There are two issues that the truck has at this point. First off the guy I got it from said that the #1 injector was sticking... you have to let the truck warm up for 2-5 minutes or it bogs down and has no power. After it warms up it runs like a champ. It only has to warm up on first crank of the day after that its fine. Is this a common condition with these trucks, should I be in a hurry to fix it or wait till it gets worse? Like I said it runs great and pulls a 30ft travel trailer fine after a couple of minutes. Also the cruise and horn won't work. I've checked all the fuses under the dash and they are fine. I've seen the post about the 03 7.3 with the same problem saying to look at the fuse box under the hood but where they have a fuse box I have a battery. Is there another location for the fuse box on the 6.0 under the hood that i am missing? This is my first real truck like this, so any and all help will be greatly appreciated.

Thanks in advance

first try a can of sea fome diesel fuel injector cleaner,pour the can in a full tank of gas,if this dont clean it out replace it asap,it will throw out different codes threw the ecm.for the fuse box under the hood it should be on the driver side fender well,if not open driver door look at side of dash for access pannel for fuse box.
