I installed an aftermarket stereo into my 84 cadillac deville, and in doing so I accidentally allowed some of the wires to touch, then I heard sparks and a short. Ever since then, several lights do not work including: dash lights, fuel management, AC/heat and the "day lights" by the headlights. I've checked the fuses, and they all seem to be fine.
Any ideas as to what this might be? :hmm:
Could it maybe be a blown relay or something? Just a thought...
I'm going to check the fuses for a third time tomorrow just to make darn sure thats not what it is. :bonkers:

Yeah make sure to check the fuses carefully, sounds like a fuse to me.
Other than that...are you sure all of the wires are back in the way they are supposed to be?

I'd say you blew a fuse (or more likely 2). also, did you tape off the end of the dimmer wire for the factory radio?

I verified the wires three times, so I'm pretty confident the stereo is wired as it should be. There was some slight confusion when installing, but thanks to this forum I believe we got it all cleared up.
And in regards to the dimmer wire: it was taped off and not connected to anything (it didn't seem right, but that's what I was instructed to so I did it).

Does the heat/AC still work, just not light up?

Yes, the heat/AC does still work. The numbers on the temp control panel light up, but the backlight does not.

83 service manual says 20amp fuse controls instrument panel courtesy lamps, engine temp telltale, cigar lighter, compartment lamp. I have a wiring diagram ill post when wifey get off computer. Looks like there are two fusable links coming off the junction box under the hood and 3 fuses that are involved.

The dash lights work.....YAY!!!!!!! It was a blown 5A fuse that was extremely difficult to get to. It was the I/P fuse that was blown and was causing the dash lights to not work (including spedometer lights, fuel gauge lights, temp control panel backlighting, the parking lights, and some of the tail lights). Simply replacing the correct fuse brought everything back to life.
The fuse was located in the fuse box under the dash beneath the steering wheel.
Thank you very much to everyone for your suggestions and help.
