Electrical Problem 1994 Buick Lesabre

I have a 1994 Buick Lesabre and the radio and interior lights don't work. I tried replacing the fuse under the dash, but the fuse shorts out as soon as it makes contact. Also, all the lights are illuminated on the heater / AC control and cannot be adjusted, yet the heat still works. I just replaced the alternator, starter and battery and didn't know if this could have anything to do with the problem. I also tried to check the fuse box under the hood, but there is no diagram or chart as to the fuses uses and positions. Any suggestions?

    Yes, I found the owner's manual fuse box diagram but the underhood maxifuse relay center chart which is supposed to be on the inside cover is not there.

GM usually puts the Fuse Diagram in the Back of the Owners Manual.

    They Both should be in the Manual.

We have a 1992 Buick Lesabre and the interior courtesy lights do not work.

One light...I'd check the bulb.
All the lights...I'd check the circuit by seeing if a fuse was blown.
Normally, a 10A fuse in the fuse block under the dash controls these lights...

Hope this helps...

Multi faceted electrical gremlin... Headlights (almost) constantly on. Once you turn the on they don't turn off, sometimes after disconnecting the battery they will turn off but not usually. Also, dome...

I love gremlins. ok first thing first. the headlights, you will see a fuse box in the engine compartment near the battery. remove the cover and you will find fuses and relays. if there is no label showing you which is which (look under the lid you just took off), feel them. the one very very hot is the one that controls the headlights (if they are stuck on a the time you do that.) replace that. it should sort out your headlight issue and possibly the interior lights.
now on to the interior lights. you haven't mentioned a blown fuse, i presume you did check them. same thing. check all the relays for one that is very hot, your door would be open anyways so the interior lights will be on at the time. replace that relay.
as a side note the headlight issue could be caused by the daytime running light module often bolted right to the firewall.
Those would be a good start and hopefully slay the gremlins

Electrical issue

It might be a electrical wire shorting or bad.

I had solved a majority of my problems by getting my electrical system looked at (turned out a brake wire was bad, and several needed to be replaced.)
