Default 78 Corvette Door pin switch wiring

Driver side door pin wiring has been pulled from switch.

Interior lights will not shut off.

How do you know if you have the three prong plug in the right position on the switch?

Help please.

If they won't shut off the white wire circuit is going to ground either through the body or one of the other wires. What do you mean right position on the switch ? As long as they are all on there and separated they are right.

Default 78 Pace Car door plunger

The door plunger female switch and the electrical male have three wires in a moulded plug. It seems that you can rotate the male plug and put it in a different location on the door switch.

How do you know if it is right?

I am thinking of removing the door plunger and gounding the outside. Hold the plunger in for 60 seconds and see if I have the right location.

I really do not want to create a short by doing this method.

What would you do?

All those wires are seeking ground so grounding them won't hurt anything. The switch position won't matter but all 3 wire must be kept away from each other. When the switch comes out it merely grounds all 3 wires to the metal pillar post.
Remove the switch and pull all the wires outside and remove them from the switch,wait for the lights to go out,if the lights don't go out then its not that switch causing the problem.
For your info the white is for the courtesy lights the tan is for the key buzzer, the blue is for the alarm

So the door plunger all three wires are looking for a ground to perform an operation. So the plug can be rotated, and it won’t make a difference.

I can check the switch with an Ohm meter to see if the switch is bad.

I would guess the next spot to look would be the time delay courtesy module is bad.

Will jumping the two white wires provide a bypass?

Again, I thank you for all your help.

Yes jumping the whites at the module will provide a bypass and they will operate like a non-delay system.
Your module is not fun to get to.

Default Thanks Roger

Roger,

I trace down the problem to the delay module. I had to remove the glove box. The module was tuck by the passenger side air duct.

I unplugged the orange module form the harness. I unplugged the white wires. I was able to plug the two wires together using the factory connectors.

It’s working without the delay function. I am going to look for a replacement module.

Thanks for your help.
