My 1999 Malibu just spazzed out the other day.

Here's the list of symptoms:
My daytime running lights wont switch over.
My tail lights wont turn on.
My head light selector on the column does nothing.
The fog light switch does nothing.
The dimmer for the interior lights does nothing.
My instrument cluster has no lighting.
My A/C and Heater ***** doesnt light up.
Service Vehicle Soon light is on.

I already replaced the multi function switch in the column and it didn't fix anything.

Only thing I've really done to the car is add on my aftermarket CD player.

Any ideas of where to start?

I've kind of ruled out fuses since so many things quite working at once and as far as I can see, none of them are on the same relay.

Thanks in advance!

 

Had similar situationon my 99 Malibu : Service vehicle soon light on and no running or brake lights.

Check fuses under the hood replaced blown fuse , everything works.

 

could be your auto light sensor gone kablammy, or trade the car its 8 years old
