Dashboard light not workin on my 99 olds intrigue

Replace the 2.2Watt bulb behind the dial.

What is the year make model of this truck? If it is a chevy or gm you may need a new cluster.

Stock radios have 2 fuses that run them.

Fuse 1 is usually labeled as Radio in the fuse box.

The 2nd fuse shares circuits with other devices that are powered straight off of the battery, so look and see if your dome light works, and your cigarette lighter. If either of those aren't working, check the fuse for that item. Cigarette lighters are usually listed as Cigar in the fuse box, and dome light is usually CTSY or Courtesy.

Did you check your fuses.

check for bad dashboard illumination fuse, also you should consider the dimmer switch

I am not sure about repairing the unit. Do you have a CD cleaner?
You might check with a reputable auto electronics shop, one that specializes in car audio. They may have an adapter that will allow an aftermarket radio to be controlled from the steering wheel. Rosen makes a nice am/fm/cd/dvd navigation unit that also has XM and iPod inputs. The hard part will be to find supporting interfaces and wiring harnesses to fit a 99.

Is there an Auto setting on the headlight switch?

did u hook the radio back to the ground ? an check your fuses
