courtesy lights
1984 Vet Interior light won't come on,is there a way to find out if courtesy door jam switch may be bad on the driver side.this is the only door that is open and closed constantly.Would this assume this just part of the loop but need to start somewhere. If I turn the light switch the interior light will come on.

Does the Plunger switch Pop out when the door is opened, if so give some shakes and Jiggles and see if you can get the light to come. does in passenger side work?

Mine is an 85 and it has a timer in it. It failed and when it did, I think it would only work with the switch turned also.
I ended up jumping past it. It is in the under dash area on the PS.

If you open the rear hatch does the lights work, I take it all fuses have been looked at. Just looking to see if all the silly things are looked at before Saying pull door panels to see if voltage is getting to switches and there grounds are good or look at Interior timers.

If those are the symptoms, you might want to see if the 84 uses the same timer.

In the current conditions I can open the hatch with the button in the middle console,buttons on the door are not working. If I turn the light switch button counter clockwise to get the interior light to come I can then open the hatch with the door buttons along with the button inside the console

In the current condition I can open the hatch only with the button in the middle console,both doors will not work. If I turn the light switch counterclockwise to get the interior light on I can then open the hatch with all three buttons. If i just open the hatch from the center console the light do not come on

Does the Hatch ajar light come on when open?

Hatch Light
I believe this is the Diagram you will need to help chase this down, I would look into what the hatch and lights have in common because when you put the interior lights on you are getting a pathway to release hatch.

Your description says the Interior Lamp Delay Timer is bad. Replacement timers are available. It can be bypassed by connecting the two white wires together at the timer connector. The timer is located behind the pass. side knee pad, taped to the main harness, near the turn signal flasher.
If you want to repair the module, here's the schematic diagram. My problem was Q1, which I replaced with a 2N2222 several years ago.

Just remove the delay module and replace the transistor you cant miss it, it has the heat sink on it.
Remove the clip that holds the heat sink and go to a radio parts store and buy a couple of new transistors, remove the solder with copper braid and soldering iron . Note the direction and fit the new one in the same way, bend it over and fit the heat sink and clip.
Install and smile at how cheap the fix is.
I can post what transistor to buy later when I get home if you cannot read the info on the transistor.

I had this issue in my 84 when i bought it.
What happens is the doors or rear hatch were left open to long and it burnt the little transistor up.
I fixed mine my self for a few bucks and a soldering iron, i also used a larger piece of aluminum and gluded it to the new transistor with some thermal adhesive since i had it laying around...
There is a site owned by an Aussie that explained everything... However my little thermal mod is not needed

A replacement delay timer I got some years ago from corvette central,
it did not have a heat sink on the transistor.
Mounted to board so it would not fit yes it did work, however when I was parked on a warm day I left the door open while the little woman did some shopping. Was only 10 minutes or so but when I closed the door the light would stay on continually.
The transistor had overheated, common issue the lights either stay on or will not turn off. Replaced the transistor and got it working again.
It failed a year later and I repaired my original delay timer, fitted the heat sink and a little heat transfer paste.
Been going strong ever since, even when I was adjusting the side windows having the doors open for almost an hour.
Heat sink is definitely needed unless you never leave the door open for long..... From my experience over the 20 years I had my c4 ......

Thanks for the correction!
I fit heatsinks to all sorts of weird stuff; so when i saw the little piece of metal clipped on my original chip i scoffed "i can do better than that!".
I have had my doors open for an hour with no negitive affects.
