courtesy lights
87 L98,
When I open either door the courtesy lights will NOT come on. However, when I turn the courtesy lights on with the main light switch, the courtesy lights come on. The only things that I see in the circuit other than the main light switch is the doors switches that are supposed to go to ground with the door open. That is what the main light switch does when you turn on the courtesy light with it. Are both door switches shot? I changed out the light assembly on the passenger door yesterday and the map lights work now on both doors. It was just a 3 prong plug-in so I do not think that I screwed up there. What do you think? I see that it is not easy changing the door switches or getting to them. Also the back latch releases do not work now either unless I turn on the courtesy light with the main light switch.

How in the world do you get access to the door switch? I just spent an hour droppping the underdash cover plate and could not get my hand or anything else in the small opening to even reach the switch.

It could also be that your courtesy light delay timer has gone bad. Mine did and exhibited the symptoms you describe. They don't make that timer any more, so I just made a jumper wire. Doors open, lights on, door closed, lights off. No delay. Other option would be to get one from a salvage yard. I can tell you that the timer on my 85 was located on the passenger side close to the ECM. Not sure about your year. You might do a search on courtesy light timer on this site. Can't remember which two of the three wires I had connected together. If you have a service manual, it probably has a wiring diagram that would help. Good luck.

That looks promising. I haven't even seen them listed before. Good job!

I was under the same assumption, till I was surfing Corvette Central and saw that they list it as available.

I finally found the light delay switch!!!! It was not where the FSM said it was. It was next to the ECM on the passenger side of the car! I ordered a new one from Corvette Central....7-10 days for delivery...

Check the door switches. You should be able to get to the connector with out pulling the door panel completely off. unplug the connector and jumper the connector.see what happens. If the lights come on and the hatch release buttons work, then the door switch is bad. I had this problem on my 91. I squirted some contact cleaner as best I could in the door switch and worked the switch manually for a while; plugged it back in and everything worked. The hatch release switch is enabled through the door ajar switch too. If you pull the bulb out from above the handle and put a meter on the two clips, you should have 12 volts on each pin to ground with the door open (one of the handle trim plate screws worked as a ground for me). Same with the hatch release, check each pin to ground. there should be 12 volts from each pin with the door open. I recommend jumping the door switch connector first.
