Zcrowley5549 Posted October 28, 2017 Share Posted October 28, 2017 In my 1990 Buick Reatta none of my interior lights work. Is this a common problem and what would be the best way to go about tracing it. Link to comment Share on other sites More sharing options...
89RedDarkGrey Posted October 28, 2017 Share Posted October 28, 2017 Key on, engine off- only 1 door open at a time, do you hear a CLICK when you release the door jamb (near hinges) plunger switch? If not- check your fuses. The 27 year old relay could also be tired. With engine running, take out of park. Do doors lock automatically? Any DOOR AJAR warning if you open a door while out of park? On the headlight switchpod- if you move the PANEL LIGHTS selector all the way to INT- do you hear a CLICK? Do the courtesy lights come on? Link to comment Share on other sites More sharing options...
