Default Interior Light Delay Timer

If the interior light delay timer has gone bad, would the interior lights still come on when you open the doors ???? Dave

Thnx. I changed the spare tire light pigtail, i accidentially touched the wires together when changing the pigtail. Now all interior lights work when i turn the headlight switch too the left ( interior lights and spare tire light ). But now when i open the doors i have no interior lights. But had them before ??? confused. Dave

Hmm usualy doesnt work that way.I believe on your 81 you have an extra fuse that controls the delay relay.I'll look at the book.On the earlier models this would only mean that the door switchs werent finding ground if the headlight switch was able to turn them on.

Ok looked in the book:you can check your 20 amp Gage fuse but it looks like you could have popped the relay.You can always just bypass it very easily and end up with no delay.

No the 80 is not the same as the 81 the 80 has a third controling fuse: the stop hazard fuse but since you have checked all the fuses you probably shorted the delay relay.
Bypass- the relay is over behind the glovebox liner-remove the glovebox-unplug the relay and in the connector coming from the car are 2 white wires just jumper those 2 wires.

Then one of your door switches (or door switch wires) is probably going to ground with the door closed.You can reset the door switches by pulling out the plunger and then closing the door.When pulling out the plunger the brass sleeve will come out also and when closing the door it will reset the depth.

The mechanical timer in my 77 used to blink if you left the doors open very long.

I've built a solid-state replacement that's a direct plug-in for the stock mechanical timer used in pre-78 (I think) cars. I need to gather up the parts to build one for Matt, too.

Does it work strictly on time like the 77s did?You should put together some for 78 and later and make a few extra bucks.I have several new timers for 84-85 that should work on 78 and newer.If you would like to copy one I could send one of them to you.

Bonjour forum,



Désolé, je suis français. J'utilise un traducteur.
J'ai un problème sur une Corvette c3 de 1982.
Le même que ce post.
L'éclairage intérieur, les trois lampes, toujours allumées.
Je pense que c'est le relais temporisé (voir dessin)
Il me semble avoir compris qu'il était derrière la boite à gants.
Vrai ou faux ?

J'ai un autre souci :
Les ampoules du compteur de vitesse ne s'allument plus.
Je n'ai pas trouvé de fusible HS.
Avez-vous une idée ?

je vous remercie d'avance

Salut tout le monde.

Hello forum,

Sorry, I'm French. I use a translator.
I have a problem on a 1982 Corvette c3.
The same as this post.
The interior lighting, the three lamps, which are always on.
I think it's the timer relay (see drawing)
I seem to have understood that he was behind the glove box.
True or false ?

I have another concern:
The speedometer bulbs no longer light up.
I did not find an HS fuse.
Do you have an idea ?

I thank you in advance

Hi everybody.

Hi everybody.

1st. Please check to make sure your headlight light switch is NOT turned full Counter Clockwise, you will feel a slight click rotating it right and then left again.
If this is true, this will keep your Courtesy lights on

I have modified your photo,
These wire terminals are very small so if you have the skills and terminals you can bypass the timer easily.
To bypass the timer out of the circuit simply follow the instructions below.
Unplug and remove the light delay timer from the main dash harness completely.
You will see 2 White wires on the drawing you provided.
The circuit to these White wires is 156.
White wires only...Run a jumper wire from one to another like on the drawing I modified.
Now your courtesy lights should work with no delay.
Here is a link showing delay timer location and wiring diagram: https://willcoxcorvette.com/corvette...er-board-78-82
New circuit boards are available from most Corvette vendors about $40.00 USD

Hello bmotojoe, thank you very much. I'm going to check it all out tomorrow I think. Saturday. I will come back to you all to thank you, already, then to keep you informed of the result. I'll see if I keep the timer or not. I take this opportunity to ask you, for this 1982, where is the fuse for the meter lighting? Because the bulbs haven't been lighting up either for a while Thank you in advance with a big thank you
-----------------------------------------------------------------------------------------------------------------------------
Bonjour bmotojoe, merci beaucoup.
Je vais regarder tout cela , demain je pense. samedi.
Je reviendrai vers vous tous pour vous remercier, déja, puis vous tenir au courant du résultat.
Je verrai si je garde ou pas la minuterie.

J'en profite pour vous demander , pour cette 1982, ou est le fusible de l'éclairage du compteur?
Car les ampoules ne s'allument plus non plus depuis un moment

Merci d'avance avec un grand merci

At the fuse panel you will see a fuse labeled INST LPS.
That fuse is for ALL of your dash and gauges lighting.
Upper Left side, It will be a 7.5A fuse.
Don't pay attention to the fuse colored in Red, this diagram was pointing out the fuel pump fuse location...
Check to see if fuse is good.
