C3 headlights .


The outer headlights on my 1977 C3 come on ok but the inner ones won't.
According to my manual, these are protected by a circuit breaker.
Is the circuit breaker in the fuse box?
Where the hell is the fuse box?

Re: C3 headlights .


What year is your car ? Does it have floor or column mounted main beam switch ? On circa 1980 models the headlights are protected by a thermal cut out built into the multi function dash board switch which opens in an overheat situation , breaks the circuit and the head lights go out . The cut out cools, closes the circuit and the lights come on again . This controls both main beam and dipped beam lights so you will lose all four lights simultaneously . If you only have main beam not working ( the inner ones of each pair ) then it not the thermal cut out that`s the problem .

The headlights are not fused in the fuse box . The fuse box is situated well hidden under dash to left of steering column and a bitch to get at or see clearly . You need to kneel down outside car and get your head right under to see it . Dumbest place ever you ask me Banghead

Sounds more like you have an earth / connection problem . Good luck.

Re: C3 headlights .


Presuming all C3s the same,
On low beam only one set light
On high beam both sets light

Circuit Breaker integral with the Headlight Switch

Fuse Board in the Drivers Foot well, up by the Steering Column

Best of Luck

Hi Mike,

At least you now know where the fuse box is Thumbs up but how inaccessible it is Banghead
As already pointed out though , if your outer headlights work but inner don`t the problem is not circuit breaker related . I recall having one inner main beam light not working shortly after buying my car . It turned out be a dodgy connection .
Start by lifting the hood / bonnet and check inside nose of car for loose or dropped off connections at back of lights . As with all plastic cars good earthing to chassis critical so unbolt any you can find ( and reach Laughing ) clean the contact surfaces and give a squirt of WD40 before reconnecting .
Of course it just could be something simple like bulbs have blown !

Many thanks for that - I will continue the battle Smile
Of course it may be that the switvh is faulty - the one that sticks ouit of the left-hand sic
de of the steering column and also works the wipers and washers and indicators.

Re: C3 headlights .


When i got my 1978 C3 i had the same problem with my lights.
Someone had fitted a fuse under the dash but behing the centre console at the top i could just feel it but not see it took ages and it only had a 15amp fitted.

Many thanks Arthur.
I've been told that both sets of headlights work through the same circuit breaker. If this is the case then my problem is not a circuit breaker but maybe a loose connection because the outer pair come on but the inner pair don't.

Re: C3 headlights .


Mike ,
You might find when you do get all four lights working simultaneously that the current draw causes the thermal cut out to keep tripping out causing lights to flash on and off .Unless a previous owner has wired relays into the circuit to prevent this . It is a C3 trait and many club members have gone that route .
I have not got round to doing this but because the rheostat built into light switch that dims instrument lights had burnt out I needed to replace that . I found that Zip Corvette list an " upgraded thermal cut out " head light switch claimed to overcome the on off flashing problem . I have just fitted one last week and initial tests seems to show it works .
