'93 Buick LeSabre - Blown Fuse, Or Something Else?

Post by Clayton » Wed Mar 08, 2017 8:33 am

I have an older '93 Buick LeSabre, which is generally in pretty good shape mechanically. Last week I drove it to work and when I went to drive home that night, the car started normally, but when I turned on the headlights, the dashboard light lit up briefly and then went out. I managed to get home okay, although I later discovered that my tail lights/brake lights were no lit (although I think the actually brake lights were illuminating when braking).

Of some diagnostic significance, was that when I shut off the vehicle and got out of the car, the warning chime was sounding, as it would if you had left your keys in the ignition or left the headlights on (and yes, I had my keys and the lights were off).

I pulled the fuse for the tail lights from the under dash fuse block, but the fuse was still intact. I pulled a number of other fuses (but not all . . .), and didn't see any of those fuses blown. I'll admit that I'm confused about what's going here. I would have guessed the problem was fuse-related, but now I'm not sure. Any next steps or further diagnostics others would suggest?
