My chevy tahoe's interior lights won't turn off

SOURCE: 2000 Chevy Venture shows gas gauge as always full..

if the remote works but the switches inside the van doesn't then the most likely fix would be the switch, tthough it is strange that both would quit. the place too start would be pop out the switch with a small screwdriver and disconnect the connector. the top left pin and the top middle pin is the unlock circuit in the switch. check continuity with your multimeter while pressing unlock. if no continuity, then get a small piece of wire and jump those pins in the connector,( the top right and center ) you should hear the doors unlock, then you know for a fact that the switch is bad. the unlock is used more than the lock so it is a more common failure. you can also use a continuity test on the rear wiper switch. though it is more common that the motor would stick from not being used. hope this helps if you have any more questions i am glad to help... dustang

Replace the rear door pin-switch if needed after testing proper operation.
It is telling the alarm the door is open all the time.
Most likely corroded terminals or wire.

I had this problem, and to be honest, it happened to the left side about a week later...it's the board that the bulbs plug into...it's a very common problem with this model. So popular that you can normally get the socket board off the shelf at a parts store! it's extremely simple to replace, and I replaced all the bulbs at the same time!

Try pressing the switch by hand and see if this turns it off, if so try some packing on the door where it contacts the switch
