Ok I have a problem. Coming home today it was night time. Suddenly I noticed I have no dash light or lights on the radio. The radio is working as is the heater, blower. The turn signals work as do the brake lights. Dome light works when I flick the dimmer switch all the way to the top. The temp console is not illuminated. The door look lights are also not illuminated. The headlights come on when I flick the headlamp switch to headlamps. I just have no dash lights. The gauges all work but are not illuminated. Wipers work. My car just has no night time lights. Any helps is greatly appreciated. I pulled the fuse for the headlamp switch and replaced. Still nothing.

 

Is it just the interior illumination lights (gauges, radio, window switches, etc) that are not working? Sounds like the ILLUM fuse has blown. What are you working on?

 

Yes exactly. They are not working. I have a 1998 chevy blazer. Also when I turn the car on at night none of the parking lamps front or back come. the work however when i put the flashers on

 

just changed illum fuse and still not working.

 

Ok, I could not determine if you also meant that the exterior park lights were not working as well. Let me see if I can dig up a wiring schematic to see how these systems have in common.

 

Yes the exetrior lamps park lights are out. However as I said turn signals and flashers work as well as brake lights. Any help you could provide would eb greatly appreciated.

 

Check the PARK LP fuse in both the underhood fuse box (20A fuse) and in the fuse box on the side of the dash (fuse 5 - 5A).

The turn signals are powered separately.

 

that is exactly what it was. the one under the hood had blown. THANK YOU VERY MUCH

 

No problem. Now, if it blows again, you have to find the source of the problem... That probably will not be as easy!
