I have a 1999 GMC Suburban. Since purchase, the dome lights have been trouble. They remain on at random, can pop on in the middle of the night, etc. We've had a few of the door switches replaced (drivers, rear window), but have not been able to cure the problem. To get around it, we keep the dome override button engaged. Any chance that this is a known, systemic problem with this vehicle? Or most likely cause one of the remaining door switches failing?

Thanks

take w-d 40 to all the door hinges and latches v and keep opening and closing the doors probably back hatch doing it I had a windstar van did the same thing after having all the switches replaced still had same problem could take more than one can but when the lights are on is when to do it.

Suggested Repair

Start with the remaining door switches, since that is the cheapest likely cause of the dome lights staying on.

Conversation Summary

The owner of a 1999 GMC Suburban reports dome lights that stay on at random, including overnight, despite replacement of the driver and rear-window door switches. The override button is used as a workaround. The expert says a remaining door switch is a possible cause and the cheapest place to start. Another user suggests applying lubricant to the door hinges and latches, especially the rear hatch, and repeatedly opening and closing the doors while the lights are on.
