Courtesy lights stay on my 1994 c4
Just bought this torch red c4 and the inside lights stay on for 15 minutes period ----doors open or closed --night or day --key on or off It's not the dimmer switch, and not the door or hatch switches. Can disable by pulling fuse #37 and #38 (which kills the radio)(I could just pull the bulbs) but I hope someone knows about this . I suspect a relay or timer. Would be ok to bypass defective module if I knew what it was and how to do it. Many thanks.

Welcome to the Forum :cheers:
I had the same issue but it could be a couple of different things so like Rick T said the C4 forum is the place for the answers and they will get you fixed up. |
Thanks

DAMMIT! I was hoping for an answer here... lol I'm having the same issue with my 93. But it doesn't always do it. I've checked the 3 door plungers, and they're all adjusted pretty well, I think. The DOOR AJAR light does NOT come on when the courtesy lights stay on, either. It's so annoying at night! Just tonight I was coming up the highway, and *bink* - they shut off! >:( Weird. I'm trying to find a sort of pattern.

The courtesy lights are turned on by the light switch (full CCW rotation of the headlight switch) or by the courtesy light delay timer which turns on the light relay when any of the LH or RH door jamb switches are activated by opening the door. The door jamb switches ground the light delay relay coil. The causes of the courtesy lights staying on is either the light switch, the door jamb switches, the wiring to these switches being shorted to ground or a defective light delay timer.

I think it's more like a minute before they go off. It sounds like a defective light delay timer to me too. If you have a FSM (factory service manual) I would try troubleshooting it from there. Good luck and welcome to the forum.

But if you leave the door or hatch open, the lights will stay on a good 10 minutes before the timer shuts them off. Above is for my '96 anyway. |

I have a similar problem with my 95 convertible. My battery would not start my car the other day. I checked the cables, and one was dirty, but before I cleaned it, I checked my warranty and found the battery was 6 years old, so I took my other car to work, and picked up a new battery on the way home. When I got home, something in the car was clicking. I replaced the battery, and now the interior lights will not turn off when I walk away. They turn off when I start the car, like they are suppose to.

My lights are fixed now. I tried the suggestion of checking if the door key slots were straight up and down, and they were, but just for grins, I worked the key back and forth a few times, on both doors, and now the lights function as they should. Thanks to all who made this suggestion, on many threads. The CorvetteForum rocks.

Old thread but glad I caught it...Thanks Indy...same problem here with the ctsy lights on all the time but did the Key jiggle in the doors and presto..(Man that was killing me along with the battery)
|
I am glad it worked. I have used it a few times over the years.

I believe the timer is supposed to shut off your lights after 10 minutes as long as you don't open the door again.
