Ok,
Removed bumper, checked all wiring running length of inside the bumper (pain inthe ***!), re-wrapped all with 3m tape for future battle with rubbing.Checked wiring with meter, all good.
fuse is still unblown and receiving power.
installed new relay.... nope

Green indicator light does NOT come on and I put in a brand new switch to the tune of some serious $$$ for not working (no returns)

This is driving me banannas as being as I have serious issues with blown lights (read nutso!)

Can someone please offer some insight, or is a completely separate remote switch the next financial step for this fu%king thing.

thanks in advance.

 

How did you test the bulbs?
Wiring, power, power at the fuse box? Multimeter, etc?

It seems like you should be able to trace power back if you don't have it to the point where it is not happening. I don't recall for sure, but there are fuses in the cabin, and under the hood. Check the manual and see where there may be related fuses.

 

Checked with multimeter and being new.
Have checked all fuses all relays.
Not my first rodeo. Only other thought is removing fuse box in engine and tracing from there.
But really, re wire a 12$ remote switch.

 

You might carefully inspect the wiring behind the lights themselves. There have been multiple reports of them rubbing and shorting out.

Link 2E (30 Amp) in the battery junction box is the common fuse for the front and rear fogs.

One report:
Removed both front fog lights checked one bulb, found and repaired the worn wires on the chassis member behind the nearside unit but couldn't detect any power going to front units.
Haven't done anything at the rear. On the basis that no power nothing happening at the front that it's a 'system' error somewhere and not four blown bulbs!

Another report:
started by taking the lamp units out and found the fault straight away. The wires had worn through and shorted out on a metal part of the body work seam. I taped up the wires and put a 4 inch split rubber hose over the offending sharp metal to stop it happening again.

Thanks yall,
Just to reiterate, I have checked ALL wiring unless it was under the engine fusebox and glove box fusebox.
Again, I am getting power at the fuse (not blowing) and no power at the relay.

Is the BCM responsible? bad... need to be re programmed?
Is there a fusible link for the front fogs? rear fogs work fine.
Am I the only one in the forum having this issue? I wish it was chaffed wiring, would have been done days and days ago.
Thanks again,

 

Mine blew a fuse once but replaced it and never happend again. Other than what has been offered, I don't know what to add. I don't see what else you can do other than check under engine fusebox or glove box fusebox. I have had wires short under the engine fuse box on previous non Rover vehicles that were a total nightmare to diagnose. Or you could just not use your foglights, that's way easier.

 

I see you said you inspected the wiring harness to the fog lights.

Early LR3's often suffered from the fog light wiring rubbing on some metal bits right near the fog lights themselves.

As such, finding the chaffed part was not too hard and could sometimes be repaired without removing the bumper or anything difficult.

In other words, I would be looking again at the first foot of so of wiring behind each fog light.

 

He's got the left tail light missing!

 

Left tail light missing? UNSEENONE, what is that?

Thanks everyone, I do suspect it is a under the engine fusebox, I literally have checked the wiring from the plug (behind pass side headlight) all the way through the bumper (removed entire bumper.) I unraveled all the black tape and inspected, metered out and re-wrapped and clipped back in place and re-installed the damn bumper and the rest of the headache.

I thought maybe headlight bright switch faulty.. reading the brights were on but I really have no power to the relay itself.

I will be ordering remote wiring kit with a fob and hardwire it myself. can control them with brights on If I have to or use as driving lights, either way the ONLY issue so far that has ever stumped me out of my 7 Rover ownership.
I hate electrical problems!!!!!
