1997 Chevy Tahoe Interior Lights Not Working. Or replace both door jam switches and check for a bad fuse. This is typically a problem with the BCM body control module Use of Dealer Scan Tool is needed to test the BCM as the only DIY is Fuse Dome Light Ground.
Make sure to have the interial light all the way just before it clicks to keep the lights on all the timeIts not labeled and I bet that button got pushed by accidentally pushed allowing the inside lights not to turn on when a door opens. I have a 1997 Tahoe LT with some lighting troubles. Thats the on and off control for the dome lightslook carefully you will see the light symbol on it.
In general you will want to try rotating the dimmer if there is one and try it in different positions.
I have a chevy tahoe 1997 4x4 4x4 does not work fuse is good tried new switch still not working. When I test drove it things were fine brought it home washed it then parked it. Now they flicker on and off quite a bit. Push in is off push out its on.
