my fog lamps on my 1999 ram 1500 sport, quad cab 4x4, they stop working all the time. first time was told it was fuse, second and third was ground, checked fuses all ok, checked relay thats ok, not sure where to check to see if it is a ground, mechanic i had fix it the other times can't remember or won't tell me. want to fix it myself so i know where the problem is..so next time i know where to start.
thanks, jerry

 

The switch in the truck could be bad.

 

When you turn on the foglights, does the small light on the switch panel light up telling you that the lights are on? When i first bought the truck, the fog lights didnt work. That didnt light up either, so i replaced the switch. They worked after that. Than about 8 months later they stopped working again, but that little light was lit on the switch panel, so i looked into the wires and found a broken ground which ran to both the lights.

 

yes the light at the switch is on..so i'll start by checking ground wire from lights.
