The complete electrical system for my 1994 honda accord lx sedan is failing. First my a/c and the fan that blows the air in, then my mirrors, then my windows, then power locks. nothing works except my stereo. Would anyone know what could be the cause of all this? if not, does anyone know how to check these problems or would i have to take it to a dealer? i checked all the fuses, and they all work. I also switched my driver's side switches bc they wernt working.

Also, i need an idler shut-off valve. Does anyone know of any places i can find this?

 

Do you have an electrical diagram for the car? If not, buy a manual or download the diagram at Hondahookup, then troubleshoot. You probably just have a bad ground or two somewhere.

I'm not sure what you mean by an idle shut off valve, but if you mean an idle air control valve, they can be cleaned out and reinstalled, or find a used one or buy a new one at the dealer.
For parts diagrams and decent dealer prices look at Majestic Hondas site.
