Boost Gauge Stopped Working

On the little computer in the 97' to 03' Grand Prix GTP's, there is a boost gauge. Mine stopped working? Anyone know how to fix this?:th_scratchhead:
 


Have you made sure that the belt hasn't slipped off the S/C? That is were I would start.

The next thing I would look at is the BBV.
 
The display in the DIC is a digital display, and just backlit by bulbs. So the entire screen would be out, not just the boost gauge.

Couple things to check would be the MAP sensor and the boost bypass valve for correct operation.

If its lit by bulbs then it may be segmented in the back. Ive never opened one up so i dont know what it looks like.

Just throwing some ideas out there.

I just had mine apart. It is segmented. But think about how the boost gauge works. Do you really think there is 6 separate bulbs for each boost bar?

Let me tell you, there isn't :th_winking:
