I have a 2003 dodge ram quad cab 1500 4.7l v8. One day i turned on both my lights and my fog lights (yes it was foggy) and when i got out and turned them off the dome lights stayed on along with the parking and fog lights, and that annoying dinger wouldn't turn off, and the weird thing is my main lights will turn on and off! So i pulled the fuses for the fog and parking lights and just been riding around with my lamp lights on and every time i open the door the dinger stays on. I turned on all the lights and pulled the plug out of the switch and the still are staying turned on.

I THINK MY RAM IS HAUNTED. PLEASE HELP

 

It could be a bad switch...

 

You might try reseting the computers, the FCM (front control module) operates all the stuff giving you problems. Its a good place to start. You may want to download the FSM from Weedahoe, its in his sig, first and study up on the circuit arrangement ahead of time. You should also check for any dtc codes BEFORE you reset the computers, they don't always turn on the MIL light. Record any codes prior to the reset, so you have somewhere to start, the dtc codes are also in the FSM in the back-------and its FREE!

 

stuck relay?

 

I'm thinking under the fuse box is corroded. Common as these trucks age...

 

Most likely its the switch, I had that happen on my 02.

Looking at the Fuse box under the Hood like Hammer said look underneath that for corosion, I had a Realy screw up on me and i had a similar problem, and last but not least id look into getting a new switch( My fogs would randomly come on i took the switch apart and cleaned it fixed that ONE problem)
