95 Corolla fog light problem

Dilbert75 · 07-08-2013 8:56pm #1

My brother brought his new 95 Corolla for its NCT and, after a few prior jobs by me, it failed only on the rear foglight. Never thought to check it but surely it's only a bulb?

Wrong. Put in a bulb to the left hand side of the right rear cluster. The switch is working - the dash light comes on but the bulb doesn't.

From the switch I expect to find a relay, because there are 4 real light wires that don't seem meaty enough to power the fog light - next best guess is that the relay needs replacing - but I'm fecked if I know where to find it. Any ideas?

If the relay isn't to blame, where to next? (Apart from an auto-electrician)

Make sure your not on "full beam" at the front, some foglamps only work on the dipped beam setting.

Is there power at the bulb holder?
Could be a bad earth?

Not on full beam but I never knew some cars had such an interlock!

No power at the bulb holder.

If you replaced the cluster with a spurious one it may not have the wiring right, we got one before and we had to rewire it. It had 2 brake bulbs and no fog (like a Japanese one) came from motor factors.

Never heard of rear fogs that only work with dipped beam.

Interesting - wonder was it replaced before he got it?

Actually hang on that was the previous model.

Think that year had just the wiring coming to a bulb holder and the holders just clipped into the cluster.

Previous one had a panel with the bulbs on it that clipped into the cluster.

Sorry..

Your obviously not as old as me:D

This used to be real common, still is in the US.

Anyone know where I'd find the fog light relay?

Silly question perhaps but did it ever have a rear fog light? Is it a Jap import?

Dilbert75 · 07-08-2013 10:45pm

Not a silly question at all. Original Irish car. Don't know if the fog light worked but it has a working switch and the light on the dash works.

Check the multiplugs inside the boot.

Wouldn't just removing the switch do the trick for the nct. No fog lights, no fail?

Exactly.

Otherwise, OP, relays are located inside an engine compartment and behind driver's kick panel. And search for blown fuses.
