I have a 2000 ranger and the right low beam went out, we changed the bulb to no avil. I thought it might be the light switch so we changed it also ,nothing!! We have checked the only groung i can find for thr lights (on the driverside under the fuse box under the hood). This problem has me stumped . Another problem that may or matnoe be related is the cargo light doesnot work either. Can anyone give us a hand?
