i was working on installing a stereo on my '01 grand prix gt and i pulled the dash off, and pulled the factory radio out and when i put them both back in, the radio display doesnt work and the light on the foglight switch doesnt light up when you turn the headlights on. Im puzzled, because the dimmer still works and all the other dash lights still work except for those 2....does anyone have any advice? thanks

 

For the radio display...it is a small bulb behind the radio display the burned out. Try and find one at a junkyard. Pontaic dealers do not carry them. I have the same problem.

 

You can replace the bulb and the dealers can order it you just need the part number. For a 2000 Grand Prix the part number is 16208443, they cost about $10. This is what I had to do with mine because my display on my radio went out.

 

I bought my bulb from ebay, user (ann_abelle123) which is made by GM. It worked perfect and shipped out super fast. It only took a couple of minutes to install. The bulb was around $20 bucks.[/align]

 

Thanks you got me going in the right direction.

A little more searching found this site

The bulb is available from Radio Shack for $2.19
