The fog lamps on my 2001 D will only come on when the light switch is in the running light position. They will not power on when I have the low beam headlamps on.
I've checked /replaced fuses, relay, bulbs, and lamp switch with no success. I've also checked the ground and wiring harness from the lamps back to the fuse box and found no problem. I can cross the relay contacts at the fuse box and they will light. Could this mean there is a problem in the fuse box itself? Has anyone replaced the box itself?
I priced an OEM fuse box for replacement and all they will sell is the complete wiring harness from headlamps back to the lamp switch for $1450.00. I'll live with the lamps in running position only if there are no fixes / alternatives.
Thanks everybody for the advise.
