Are you sure the lights are not coming on during the day as well? They are kind of hard to see during the day.

Are you sure it's a half hour and not just 15 minutes? My hatch switch used to cause this with inconsistent performance and I just unplugged the damn thing. A door switch could cause it too if it gets out of adjustment or otherwise goes outa' whack. BTW, 15 minutes is the timer setting that will turn the lights out if the door is left ajar or whatever.

Assuming you shut the car off and close the door, yes they stay on for a while. My 92's at about 10 minutes.
But this also happens in daylight. As far as I can see in the FSM, there's no separate timer. It may be in the CCM. Note that your interior lights should turn off after this time period even with a door open. But, if you leave the hatch open, they won't turn off at all, at least until your battery goes down. |

Au contraire. Before I unhooked my hatch switch, the lights would also go out after 15 minutes if the hatch was open, just like if a door were left open. The timing that turns the lights out maybe 30 seconds (?) after closing a door or the hatch is a separate function from what I described and from I believe may be causing his problem. And yes, I believe both functions are ultimately controlled by the CCM. But I'd still check the switches first, unhooking them one at a time if necessary to isolate which one may be malfunctioning.

The hatch thing might be model specific. My 85 would stay lit after the hatch was open.

Most definitely a possibility. Did the early cars even have a CCM? |

Under low light conditions, the interior lights stay on for 20 seconds after closing the doors/hatch on my 91. I had aproblem where they wouldn't shut off. It turned out to be a relay under the dash near the glovebox that was sticking. You can hear it.

I am guessing this is in the door lock or ignition cylinder.
You see, when you unlock the door, it turns on the lights. Close the door, the interior lights stay on until the key goes in, or, 15 minutes times out. If the car has higher mileage, blame them... they both control the lights and could simply be worn out. I have a lot of miles on mine and this is quite common with my interior lights, too. |

Dear All - thanks so much for the huge response - seems I'm not alone in being lit up like a Christmas Tree after dark [A1] Yes - sure of it - my girl and I laugh at this irony everytime [A2] Yes - I would guess even longer (last time they went off it was when we were on a very dark road at night) was about 45 mins into our journey [A3] Sounds similar - but mine acts fine during day [A4] You kindly wrote "turned out to be a relay under the dash near the glovebox that was sticking. You can hear it." ... sounds promising - I will listen for such a wining relay - do you by any chance recall the relays name/function and I should be able to have it tested as the fault [A5] We are in the same boat then ..... miles are low - 38,000 [A6] This too sounds like a possible culprit - are they pricey to replace? Many many thanks for all your time - as always it is much appreciated cheers!!! |

That's interesting, on what year? I do get the 30 sec. turn off with the doors closed. 15 min with the doors open. But the lights stay on with the hatch open. I remember someone mentioning this elseware, it's been a while. Maybe both our CCM's are goofy. I also think both functions are controlled by the CCM. It drives me nuts that there's nothing in the FSM about it. Another thought, if the hatch lights turn off in 15, what's the purpose of the extra part on the aftermarket hatch vents that hold the switch down? Well, just walked down to the car and answered this I think. With the hatch up the security lite keeps flashing. |

Dear All
Just wanted you all to know this is now resolved (thanks for your many responses (helped me rule out a lot of things) Turns out it was down the the key lock in the door - when I unlock the car with the key (by turning the key clockwise 90 degrees) I can pull the key out of the car (while the key lock position is still way to the right - if I leave the key in this position then the lights stay on, however if I unlock the car and ensure I return the key to the straight-up position then there is NO problem with the lights at all just hoped this may help someone else someday... thanks again for all your time |

I suspected that... and I am not surprised. Mine does this and it seems to be related to the door lock.
Glad you found it!!! |
