Ever since i got my ranger the foglamps havn't worked, it doesn't look like the bulbs are out. I have a feeling the fuse blew, the manual doesn't say which fuse belongs to the fogs. Truck is an 04 ranger edge.
i'd take the plugs off the back of the bulbs and test to see if your getting juice through the plug. you could use a normal test light and ground it to the frame or just anywere you can find near by. if your getting juice in both plugs then your bulbs need replaced.
Hey I've got the same problem with my 04 Ranger. Does your turn signals come on full when you turn the headlights on but not the fog lights, cause that is what mine do. I tried all the fuses to no avail. It seems like a relay problem to me but I don't know
