Fog Light problem, no electricity deliver to light bulb

jwa · Post by **jwa** » Mon Apr 05, 2010 9:48 pm

Hi as the topic I can not turn my fog light on,

I have check the fog light fuse also every single in both fuse boxes, no blow fuse

and test the curcuit with multimeter there is electricity running through the fog light fuse,
but when I test the positive(power), negative(ground) cables there is no electricity reading (on both fog light plug)

my one is pre-facelift so the plug come with the dimmer and indicator ,
the dimmer and indicator are working fine.

P.S. when I press the fog light button, the speedometer light does come on.

Anyone got an idea?

They need a working bulb to complete circuit i believe so may just need simple replacement, otherwise start tracing back to see where power is being cut

just replace both light bulb but still not working....

does anyone know if there is any "extra" fuse link to the fog light button, or relay..?

where would the relay locate?

Just spend few hours testing the terminal,
the 15A fuse for fog light is good,
when turn the fog light on and took that fuse out test with multimeter read about 11.60v,
so does it mean the fog light switch inside the car is working?
because i has power going though the fog light fuse.

On the otherhand when turn the fog light OFF and took that fuse out test with multimeter read 0.0001 is nothing.

Also tested the dimmer '+' , '-' wire, both are working
then i put the multimeter on dimmer '+' and fog light '-'
still can read about 12v, therefore the '-' wire on fog light plug should be working

Now does it mean all come down to the '+' wire in between the fuse box and the light plug?
How could both side wire fail at the same time....

Are you sure the switch is OK. If the switch has burned out (which is a fairly common fault, it can sometimes take the plug out as well. Are there any scorch marks on the plug at all?

No, there are no scorch marks at all, but full of grease and it is dirty....

My money's on the switch too. I've burnt out at least 3 coz cbf installing a relay so I don't bother connecting it up now. Run your multimeter through the switch.

Fixed Thanks guys,

should be the switch problem, I just add a relay and control by the other wire in the switch.

Just another question dose any have an idea about what "part number" this would be
dstock maybe?

http://www.camskill.co.uk/products.php? ... 0s248p8104

it show Manufacturers Part Numbers for REF ONLY MR114085

but when i take it down to 2 different Mit dealer they say "part number not exist"

gessing the part number dosent exist cause of the fact aus didnt bring out the ftos so any parts for the ftos arnt in there data base only parts they have are shared parts with the lancers personly ild buy threw camskilll rather then dealers , dealers charge like 3 times more then the part is worth ive delt with camskill befor bought a big box of stuff costed 100 dollars to ship
