W202 C230K Estate - Problem with fog lights

[merc_w202]

Hi there,

Ive got an unusual problem on my bumper mounted fog lights on my C230K,

Ive recently bought the car so im unaware to when the last time the lights worked,

The fog lights dont work full stop, bulbs are fine,
there is 12 Volts flowing to the sockets and the connectors when I connect the multimeter and switch it on,

But the moment I plug the bulb in and try it, the voltmeter reads 0v which means the voltage is drawn away as soon as the bulb is plugged in!
Ive tried different bulbs so I know its not an issue with bulbs,

This one has definitely got me stumped, and Ive reached a dead end
I am unaware if there is a relay or a switch thats causing the issue?!

Has anyone else come across this issue?
Anyone know how to fix it?
Any help is much appreciated!

Don't use a multimeter to check for a feed. Use a testlight.
Sounds like a fuse/switch problem to me.

It sounds like poor current flow. Check the connectors and wiring for corrosion. Corrosion is a common issue in this area.

Did not think of trying a test light will try that next as well,

Ive checked the immediate connectors for the bulbs for corrosion and I cant seem to see any,
Gonna have to check the harness coming from the headlights to see if there is any issues there!
