Why would headlights on a Cadillac Catera not go off?

Answer 1

Don't know the circumstances for the question, but if the headlights were turned on manually and then won't turn off when the switch is turned to the left, the problem is with the switch. If you place a screwdriver about halfway down on the left side of the switch module (put a piece of cloth between the screwdriver and the instrument panel) and then gently pry out the switch module you will probably find that the metal clip on the right side is not right. I had the same problem with mine and I think the switch depends on those clips being positioned properly. If you look at them the clip pushes on a spring. I think that spring aids in the return of the switch. When reinserting the switch, take the side panel off first so that the connector can be held while the switch is inserted otherwise it probably won't connect. If you're not 'handy' find a mechanic. Here is more information from another FAQ Farmer: The headlights stay on due to the Twilight Sentinel Feature, Adjustable time delay just below the Headlight Switch. If they stay on until the battery dies, it is probably the Headlight Relays (2) Sticking. These Relays are located in the Fuse Box. The Dealers sell you both of them in one package right away. This makes it sound like it is a common problem. Both Relays are about $40.00. A quick way to get the lights to go out that I used was to hit the Knee Bolster Pad with a closed hand a few times right over the Fuse Box, the Vibration released the sticking Relay, Good Luck!
