1998 C5 Euro Spec - Rear fog lights not working

[VantaR]

Hi guys,

Will keep it short. One of my rear fog lights do not work. If it is the bulb, how do I get the cover off without breaking it?

If it's anything else, what steps do I need to follow to diagnose it? Thank you!

POA

Being the fog light lens has no mounting screws,
I suspect you need to go on the backside and the light socket plugs into the lens mount,
so just have to pop the socket off and replace the bulb

If not the bulb than follow the wires, and maybe it is a ground wire issue

Part of me thinks you're right but also, it could be that the cover comes off from the outside, is there any guidance on this online? I've been looking and i've misplaced the owners manual..

As to GM is as I thought, if you have GM Euro spec C5
from the backside, turn the fog light socket and pop it off to get to the bulb

Aha makes sense!

Any idea what the bulb would be?

I do not know Europe bulbs but if you pop the one-off, the part number would be on it and
assume most auto parts in UK would have them
If that one did go bad, suspect the other side goes bad soon so you should buy a couple of those bulbs

The one you suspect bad is closely looking at the filament in the bulb to see if it is blown or broken

If your C5 was sold by GM as for Europe, then look in the owner's manual for bulb specs should tell you
the part number for that bulb

Found a 1998 C5 owner's manual from a website in the UK, so assume this is what you need

Do not try to pop the lens off , they have plastic pins attached to them and break very easily . If I can remember you reach the securing bolts via the number plate mount ( I may have got how to reach the bolts wrong as it’s been 20 years since I had to do mine ) but definitely do not pop out. . Cheers

PS mine was a 1999 UK car , just in case yous is slightly different . Good luck .

I may be wrong, but securing bolts via the number plate mount that could be a US rear end and not a Euro spec but only a thought.

Hi Ian I have put in another post (C5 Headlights) I don’t think there really is a UK spec C5 Corvette just a Euro spec C5 Corvette with EXP T85 headlights.
