99 Tahoe Interior lights

The interior lights will not go off after closing the door. I have repalced the whole head light control assembly along with the door switch. With the new control in and the over ride button puhed in the light will stay off. Any Ideas???

I had the same problem with my 1999 Suburban. I found the driver side door switch was bad. I replaced it and the inside lights worked fine for two week then the problem again. I then replaced the same door switch with a new one and the lights have been working fine for the last year. I switches are cheep and bad. You might have a bad switch again. Dave

P.S. Your timer might be bad and not releasing after it should. Dave
