Re: Rear interor mood lights on 89 vendura van
Pull the light and check for power and ground at the light connections. Failure on either side will tell you where to look. If you have power and ground there, suspect the light or connections after the test point. You can test the bulbs with an ohm meter. There should be resistance between the + and -. Sometimes a bulb will appear to have an intact filament, yet still be defective.
Are the lights standard type bulb or florescent? I'm not up on Van type mood lighting.
