fog light issue

I'm having an issue with one fog lights working intermittently. Some times it's just fine other times it's off. I changed bulbs and swapped bulbs side to side. Only the passenger side has this issue. If I manipulate the wires where they plug to the bulb it comes on. I assume there is an issue with the plug, wires or harness.
Does anyone have any of these parts they aren't using? Or know of a place to get them? Or an idea on how to fix this?
Any help would be appreciated.

 

First thing I would check would be bad ground wire. If that does not fix issue, then try to clean terminal as there may be corrosion.

 

Do you think each fog light is grounded separately ? I will try and trace the wires from the harness. Thanks

 

And what do you suggest to clean the terminals? Wd40? Or should I get some electrical contact cleaner?

 

Plug is junk,mine done the same thing,passenger side.

Sometimes it would work sometimes not.

 

Mine Is also passenger side. Did you find something solution ?

 

I cut the plug and solder the wires..I have hids so this may not be something you can do with factory lighting..but my problem was the factory plug it self,not the hid wire.

If you don't want to do that you should be able to get a new plug with the wires,just cut the old and put the new in.

Dealership worst case or you can look around on the internet maybe eBay.

 

I'll look into a new plug and splice it in if cleaning doesn't work. Thanks

 

This is what you need if memory services me right.

Yup that's it. Thanks man

 

i bought a new plug on Amazon and replaced the old one, which was melted a little and had a loose wire. working fine now. a $6 fix

 

Reviving a thread here, but this was driving me crazy for the past few months. Bulbs kept blowing, couldn't figure out what it was because it all looked good underneath. Plug looked OK from quick visual, but just last night I finely replaced it using the ones from Amazon, and BAM, fog lights working again!

Good to note, buying from amazon comes with full harness and connecting pins, but if buying from dealer it only comes with the harness, no connecting pins, and is twice the price!
