When I first bought my 91 RS, the dome and hood lights and horn didn't work. I took it in to get some other stuff fixed and they went right ahead and fixed the lights and horn without charge or even me asking them to do it!

Now, on with the story...Today I was replacing my headliner so I had to take the dome light out and everything. While I was trying to get the metal retainers off, the light went out. Curious, I looked under the hood and that light was out too! Wiring looked good. THEN I tried the horn and it didn't work either. Are these three items electrically connected some how? What do I have to do to get them back online?

 

ok look in the fuse box. its a 20, and if you have your cigarette lighter in, pull it out, that will short your electricals. i pulled mine out and the fuse hasnt blown since. just thought i would try and help

You are blowing fuses. I had the same problem. The fuse is the "ACC" fuse that controls the accessories, notice that the console light and cig. lighter don't work either. Just replace it with a 20 amp fuse and you should be fine..
