My wife just bought a 00 superduty a couple months ago. Really nice truck, I'm a dodge guy and I love her truck. I just recently I have had a few problems with it. The windows don't like to work half the time, the " door ajar" lights on constantly, cargo light stays on, and temp\compass does not work.door locks don't work. All intermittent problems. Anyone have any problems like this. I was thinking a wiring harness getting messed up or something. Its about to drive me bonkers any help would be appreciated. Thanks

 

idk, someone should chime in

 

It does sound like the wiring harness, my 99 f-250 gave me problems with the power door-locks & power mirrors and it was the wiring harness on the passenger side !!

 

Sounds like a body control module. Have is scanned for codes.

 

door locks = door lock accuators, door ajar light = sticky switchs spray the door latchs with latch lube, temp compass= comapss modual (very expensive) all common problems with a 1999/ 2004 superduty

 

Thanks everyone, now I know where to look. I had a feeling it was a wiring harness problem and was dreding looking into it. I do notice a lot of superduty trucks going down the road with the cargo light on. So I figured it must be a common problem. Thanks again

 

The overhead console's have a bad habit of breaking the solder connections on a few of the surface mounted resistors. When they get loose enough, one will completely pop off and the console dies. There are a few repair writeups on the new if you are any good with a pencil soldering iron. THIS IS ONE

The door switches are infamous for sticking which would play havoc with your lights staying on, just like you are driving down the road with the doors wide open. WD-40 is usually recommended but I don't like WD-40 for this because it stays wet and continues to collect dirt and dust. I always recommend a drying type of spray lube. Dupont has a good spray Teflon lube that will do the truck but will dry after application.

Window problems: I would guess it's a switch or motor problem. The dorr locks are definitely an actuator failures.
