Cadillac Seville / Cadillac Eldorado Forum Discussion, No interior lights? in Past Cadillac Vehicle Discussion; Just noticed today on my 97 STS no interior lights are working except the door little lights that are near ...
I checked fusses this morning one cigarette lighter fuse was blown, put new one in still dont work. Fuse is still good.
I checked the 50 fuse underneath that cover was good. Checked the power block relay has 4 wires the orange one is broke. Corroded.
Can you post a picture with what you found (the "power block relay") I don't understand what you mean. Do you have power to the interior lights fuse?
Underneath that cover on the top outer corner there is a fairly large relay mounted with the connections down. The wires connected to this relay are fairly thick (~12 AWG) but one wire is significantly thiner (~18 AWG). That is the wire that provides power to the interior lights fuse. Is that wire OK (should be double ferruled with the large wire underneath the relay terminals).
My 97 STS has the same problem - no interior dome lights, no glove box light, and no trunk light. Heck, the air does not work either. I checked the fuse & relays look good. Is it necessary to remove the plastic shroud to gain access the wires that connect to the fuse box?
