i have a 1993 chevy astro w engine with electrical problems
the left side of my fuse block is dead, horn, dome, tail lamps ect. i also have no power to the headlight switch. by jumping the head light switch with a hot wire i can back feed the left side of the fuse block. i assume i have a fuse or circuit breaker blown but i can not find it and i can't find a wiring diagram to help it leads me to a convenience center that does not exist. i checked in the engine compartment and i can't find an inline fuse
 i need to know what feeds these items from the source and where any circuit breakers or fuses would be located can anybody help
 
thanks

#11 of 152 I have same electrical problem by rastro1

The fuel pump, headlights, dome lights, and horn will not work on our 95 Astro. Everything else is getting power to our knowledge. We replaced the battery cable ends because they were corroded. We replaced a relay under the hood because it had black burned gooey stuff on it around the wire connector. We replaced a burned out blower motor resistor, and now the blower works on all three speeds like it should. We replaced the electrical ignition switch with a new one. We checked tons of wiring for burn and corossion damage to no avail. It sounds like the same problem the one gentleman was having with the left side of the fuse block not getting power to it. Any good ideas on what the problem may be? The problem seems to be intermitent but most times the van just won't start and the electical items mentioned won't work. Thanks.

#15 of 152 high beam goes black by albedo039

May 14, 2007 (4:43 am)

Hi
I have a peculiar problem with the headlighs. Driving with high beam on, it suddenly goes complete black! Switching to low beam gives me low beam all right. When I switch back to high beam, the light stays on for 20 seconds to a couple of minutes, then it goes black again. I have H4 bulbs 100/90W.
Any ideas?

I'm afraid I can't do you any good. I'm still waiting to hear from someone on my problem from over a month ago. This web site doesn't appear to be worth its weight in oil when it comes to answers. I wish you luck.

I responded to your message because it came to my email address. Once again, good luck.

Hi
Maybe I can be of some help to solve your instrument panel lights problem.
Possible cause:
1 No ignition feed to the instrument cluster
Remove the large 17 pin connector from the instrument cluster. Using a digital Volt/Ohm meter, measure the voltage from pin A13 to gnd with the ignition in run. The meter should read battery voltage. If the readings are less than battery voltage, or zero, repair the pink/white wire from the ignition switch.
 
2 No ground to the cluster
Measure the resistance from pin A15 and A16 to gnd. If the meter reads anything but 0-0.5 Ohm's, repair the black wires at A15 and A16 to gnd.
 
3 Inoperative cluster
Replace the cluster
 
If this doesn't help, check out the forum at astrosafari.com
I think the guys there are acting more alive than on here
 
Respectfully yours

PS! If you send me your email address, I can mail you a copy of the Circuit Diagram for this specific area.
